Question

Olivia makes and sells muffins and scones at

a school bake sale. She sells muffins for $0.50
each and scones for $0.80 each. She hopes
to raise at least $20. The inequality 0.50x
+ 0.80y z 20 represents the possible ways
Olivia could reach her goal. Is the ordered pair
(20,32) a solution for the problem situation?

Answer 1

Answer:

yes

Explanation:

We can substitute the proposed solution values and see if the inequality is true.

0.50x +0.80y ≥ 20

0.50(20) + 0.80(32) ≥ 20

10 + 25.6 ≥ 20

35.6 ≥ 20 . . . . . . true; (20, 32) is a solution
