write a compound inequality

a cookie contains 9 grams of fat. if you eat no fewer than 4 and no more than 7 cookies, how many grams of fat will you consume?

Respuesta :

The only way I can think of this is like...

c9 +4-7 = how many grams. so move 3 over then divide and simplify.

so 1/3 should be the amount you can eat
