Compare each mark:
In Algebra, Joe scored 20 out of 25 in Algebra. It means Joe scored \(80\%\) of the total mark.
\(\frac{20}{25}=\frac{x}{100}⇒x= 80%\)
Joe scored 30 out of 40 in science. It means Joe scored \(75\%\) of the total mark.
\(\frac{30}{40}=\frac{x}{100}⇒x= 75%\)
Joe scored 68 out of 80 in mathematics, which means \(85\%\) of the total mark.
\(\frac{68}{80}=\frac{x}{100}⇒x= 85%\)
Therefore, his score in mathematics is higher than his other scores.
Use the formula for the area of circles.
Area \(= πr^2 ⇒ 64 π = πr^2 ⇒ 64 = r^2 ⇒ r = 8\)
The radius of the circle is 8. Now, use the circumference formula:
Circumference\( = 2πr = 2π (8) = 16 π\)
To find the discount, multiply the price by (\(100\% –\) rate of discount).
Therefore, for the first discount we get: \((D) (100\% – 20\%) = (D) (0.80) = 0.80 D\)
To increase the \(10 \%: (0.80 D) (100\% + 10\%) = (0.85 D) (1.10) = 0.88 D = 88\%\) of \(D\)
Write the proportion and solve for the missing number.
\(\frac{32}{12}=\frac{6}{x}→ 32x=6×12=72 \)
\(32x=72→x=\frac{72}{32}=2.25\)
\(2x+4>11x-12.5-3.5x\)→ Combine like terms:
\(2x+4>7.5x-12.5→\) Subtract \(2x\) from both sides: \(4>5.5x-12.5\)
Add 12.5 to both sides of the inequality.
\(16.5>5.5x, \)
Divide both sides by 5.5.
\(\frac{16.5}{5}>x→x<3\)
To find the discount, multiply the number by (\(100\% –\) rate of discount).
Therefore, for the first discount we get: \((200) (100\% – 15\%) = (200) (0.85)\)
For the next \(15\%\) discount: \((200) (0.85) (0.85)\)

Frequently Asked Questions
What is a good MAP score for 8th grade math?
A good 8th grade MAP math score is one at or above the national average for the same testing season. Based on NWEA's national norms, the average RIT for grade 8 math is roughly the mid-220s in fall and around 230 in spring, and scores in the low 240s or higher are typically in the top quarter. The percentile on your student's report is the easiest way to judge.
What is the average MAP math score for 8th grade?
The average 8th grade MAP math RIT score is roughly 225 in fall, rising to about 230 by spring, based on NWEA's national norms. Because MAP Growth is on one vertical scale, the more useful number is often your student's growth from fall to spring. NWEA updates its norms from time to time, so check your score report for the exact percentile.
What is on the 8th grade MAP test?
The 8th grade MAP Growth math test covers the main middle school strands: linear equations and systems, functions and slope, the Pythagorean theorem, transformations, volume of cylinders, cones and spheres, and scatter plots with lines of fit. Because it is adaptive, strong students may also see some early high school algebra, while others see review items from grades 6 and 7.
Are there NWEA MAP test 8th grade math practice questions?
Yes. The 20 questions here match grade 8 MAP Growth difficulty, from simple interest (3.5% of $12,000 for two years is $840) to finding a circumference from an area of 64π (the radius is 8, so it is 16π). NWEA also offers a short practice test online that shows the real interface. Use both, then review every miss.
How can I prepare for the NWEA MAP test in grade 8 math?
Start with a practice test to find weak strands, then spend 20 to 30 minutes a few days a week on those topics, such as solving multi-step equations or using a² + b² = c². Since MAP is untimed, teach your student to slow down, use scratch paper and check work. A good night's sleep before the testing window helps more than last-minute cramming.
