Answer:
Step-by-step explanation:
Given that:
Johnathan looked at two different portions of cereals at the supermarket.
They are:
Sunshine Cornflakes: 24-ounce box for $4.32
Bright Start Cornflakes: 36-ounce box for $5.76
To calculate the cost of one ounce of Sunshine cornflakes, we have:
24-ounce box for $4.32
1 - ounce box will be x
x = ($4.32 × 1 ounce box) / 24 ounce box
x = $0.18
1 - ounce box will be = $0.18
To calculate the cost of one ounce of Bright star cornflakes, we have:
36-ounce box for $5.76
1 - ounce box will be = ( $5.76 × 1 ounce box) / 36 ounce box
1 - ounce box will be = $0.16
Since 1 - ounce box of Bright star cornflakes is lesser than 1 - ounce box of Sunshine Cornflakes.
