please help me im really stuck it would be a huge help

Answer 1

What is the unit rate for calories per​ cup? 120 calories.

How many calories are there in 4 cups of the​ cereal? 480 calories

Explanation:

if 3/4cup = 90 cal

then 3/4cup + 3/4cup + 3/4 cup+ 3/4cup = 3cups or 360cals ( 4 x 90cals)

and 360cals/ 3cups = 120 calories

1cup = 120 calories so

4cups x 120calories

4cups = 480 calories

Hope this helped :).

Answer 2

90 calories in 3/4 cup is the same as saying 30 calories per 1/4 cup. If we know that 1/4 cup is equal to 30 calories we can simply multiply 30 by 4 to get 120 calories per cup. If we take our total per cup and multiply it be 4 that would be 480 calories for every 4 cups.
