Question

Mitch needs to purchase soft drinks for a staff party. He is trying to figure out if it is cheaper to buy the 12-pack of soda or the 20-pack of soda. The 12-pack of soda costs $3.99, and the 20-pack of soda costs $5.48.

i. Which pack should Mitch choose?
ii. What is the difference in cost between single cans of soda from each of the two packs?

Answer 1

a) Mitch should choose second one

b) $ 0.06 (approx)

Explanation:

Cost of 12- pack of soda Cups= $3.99

Cost of 1 pack of soda cup= $
`(3.99)/(12)`

Cost of 1 pack of soda cup= $ 0.33(approx)

Cost of 20- pack of soda Cups= $5.48

Cost of 1 pack of soda cup= $
`(5.48)/(20)`

Cost of 1 pack of soda cup= $ 0.27(approx)

The cost of later one is cheaper than first one.

1) Mitch should choose 20- pack of soda cups costs $5.48

2) Cost of first soda cup= $ 0.33

Cost of second soda cup= 0.27

Difference= 0.33 -0.27

Difference= 0.06

Hence, the difference in cost between single cans of soda from each of two pack is approx $ 0.06

Answer 2

i)20-pack of soda bottles

ii) 0.0585

Explanation:

i)Cost each soda in 12-pack of soda =
`(3.99)/(12)`

= $0.3325

cost each soda in 20-pack of soda =
`(5.48)/(20)`

=$0.274

since, cost of each soda is cheaper for 20-pack soda, Micht needs to purchase the same.

ii) the difference in cost between single cans of soda from each of the two packs= $(0.3325- 0.274)= $0.0585

=$0.0585
