Question

A recipe for macaroni and cheese calls for 18 ounces of cheddar cheese to make 32 four-ounce portions. How much would cheddar would be needed to produce 40 eight-ounce portions?

Answer 1

Answer:  45 ounces of cheddar

Explanation:

18 ounces of cheddar is used to make 32 four-ounce portions.

To make 1 four-ounce portion requires;

= 18/32

= ‭0.5625‬ ounces of cheddar

Making 1 eight-ounce portion should therefore be double that;

= ‭0.5625‬ * 2

= 1.125 ounces of cheddar

To make 40 ounces;

= 1.125 * 40

= 45 ounces of cheddar
