Answer:
a)9:48
b)10:48
c)9:36
Step-by-step explanation:
Find the ratio of the number of cans to the price.
Shop Smart: 24 packs (2 for $9)
No. of cans in 1 pack = 24
No. of cans in 2 packs = [tex]24 \times 2 = 48[/tex]
Cost of 48 cans = $9
Cost of 1 can = [tex]\frac{9}{48}[/tex]
So, the ratio of the number of cans to the price is 9:48
Super Saver: 12 packs (4 for $10)
No. of cans in 1 pack = 12
No. of cans in 4 packs = [tex]12 \times 4 = 48[/tex]
Cost of 48 cans = $10
Cost of 1 can = [tex]\frac{10}{48}[/tex]
So, the ratio of the number of cans to the price is 10:48
Price Buster: 12 packs (3 for $9)
No. of cans in 1 pack = 12
No. of cans in 3 packs = [tex]12 \times 3 = 36[/tex]
Cost of 36 cans = $9
Cost of 1 can = [tex]\frac{9}{36}[/tex]
So, the ratio of the number of cans to the price is 9:36
