7. jasmine bought 32 kiwi fruit for $16. how many kiwi can lisa buy if she has $4?
8. if you can buy four bulbs of elephant garlic for $8 then how many can you buy with $32?

10. the money used in jordan is called the dinar. the exchange rate is $3 to 2 dinars. find how many dollars you would receive if you exchanged 22 dinars.

Explanation:

Step1: Determine the number of items per dollar

For each problem, divide the total amount of money by the cost per item.

Step2: Calculate the result

1. For the pineapple chunks: $\frac{10}{2}=5$
2. For the ginger jars: $\frac{4}{2}=2$
3. For the cantaloupes: $\frac{6}{2}=3$
4. For the blueberries: $\frac{9}{3}=3$
5. For the rectangle width: Set up a proportion $\frac{24}{12}=\frac{x}{2}$, cross - multiply $12x = 24\times2$, then $x=\frac{24\times2}{12}=4$
6. For the Tala exchange: $\frac{6}{2}\times6 = 18$
7. For the kiwi fruit: First find the cost per kiwi $\frac{16}{32}=0.5$, then $\frac{4}{0.5}=8$
8. For the elephant garlic: First find the cost per bulb $\frac{8}{4}=2$, then $\frac{32}{2}=16$
9. For the seedless black grapes: $\frac{20}{2}=10$
10. For the Dinar exchange: Set up a proportion $\frac{3}{2}=\frac{x}{22}$, cross - multiply $2x=3\times22$, then $x=\frac{3\times22}{2}=33$
