Speed \(= \frac{distance}{time}, 58 =\frac{2,200}{time} →\) time \(=\frac{2,200}{58} = 37.93 ≅ 38\)

22- **Choice D is correct**

Let’s review the choices provided. Put the values of \(x\) and \(y\) in the equation.

A. \((1, 4) ⇒ y = -3(1)+7=4\) This is true!

B. \((3, -2) ⇒ y = -3(3)+7=-2\) This is true!

C. \((-4, 19) ⇒ y = -3(-4)+7=19 \)This is true!

D. \((-3, 15) ⇒ y = -3(-3)+7=16\) This is not true!

Only choice D does not work in the equation.

23- **Choice D is correct**

Since Julie gives 13 pieces of candy to each of her friends, then, the number of pieces of candies must be divisible by 13.

A. \(187 ÷ 13 = 14.38 \)

B. \(216 ÷ 13 = 16.615 \)

C. \(343 ÷ 13 = 26.38 \)

D. \(377 ÷ 13 = 29 \)

30- **Choice D is correct**

To find the discount, multiply the number by (\(100\% –\) rate of discount).

Therefore, for the first discount we get: \((D) (100\% – 12\%) = (D) (0.88) = 0.88 D \)

For increase of \(15 \%: (0.88 D) (100\% + 15\%) = (0.84 D) (1.15) = 0.966 D = 96.6\%\) of D or 0.966D

Let \(x\) be the number of new shoes the team can purchase. Therefore, the team can purchase 160 \(x\). The team had $32,000 and spent $18,000. Now the team can spend on new shoes $14,000 at most. Now, write the inequality: \(160x+18,000 ≤32,000\)

35- **Choice B is correct**

To get a sum of 8 for two dice, we can get 5 different options: (2, 6), (3, 5), (4, 4), (5, 3), (6, 2) To get a sum of 5 for two dice, we can get 4 different options: (1, 4), (2, 3), (3, 2), (4, 1) Therefore, there are 9 options to get the sum of 8 or 5. Since we have \(6 × 6 = 36\) total options, the probability of getting a sum of 8 and 5 is 9 out of 36 or \(\frac{1}{4}\).

36- **Choice D is correct**

Solve for \(x. 8≤-2x+4<16 ⇒\) (subtract 4 all sides) \(8-4≤-2x-4+4<16-4 ⇒ 4≤-2x<-12 ⇒\) (divide all sides by \(-2)-2≥x>-6 x \)is between \(-2\) and \(-6\). Choice D represent this inequality.
