Question

Jalen bought 24 juice packs for $7.20. Tia bought 6 juice packs for $2.70. Which statement describes the difference in the unit prices of Jalen's and Tia's juice packs?

Answer 1

Answer:

$0.15 .

Step-by-step explanation:

Jalen bought 24 juice packs for $7.20

Cost per pack of juice = $\frac{7.20}{24}$

                                     = $0.30

Tia bought 6 juice packs for $2.70

Cost per pack of juice = $\frac{2.70}{6}$

                                    = $0.45

The difference in unit prices of Jalen's and Tia's juice packs

= 0.45 - 0.30 = $0.15

The difference in unit prices of Jalen's and Tia's juice packs is $0.15 .

Answer 2

7.20/24 would give us 0.30/1 so Jalen's unit rate is $0.30 per juice pack.
Then we take our 2.70/6 which would give us 0.45/1 which means the unit rate is $0.45 per juice pack.What you're doing is trying to find the difference, so you'd subtract .30 from .45 which gives you .15, the difference is $0.15 per unit.

0.15 is your answer
