Question

Amelia wants to sell cupcakes and cookies to make money for her vacation coming up. She needs to earn at least $125. She can sell cupcakes for $1.50 each and cookies for $0.75. She only has time to bake up to 120 treats. Which combination below will allow both constraints?

A. 50 cupcakes and 60 cookies
B. 60 cupcakes and 40 cookies
C. 100 cupcakes and 30 cookies
D. 90 cupcakes and 20 cookies

Answer 1

D) 90 cupcakes and 20 cookies

Explanation:

90(1.5) + 20(.75) = 135 + 50 = $185

90 + 20 is less than or equal to 120

185 is greater than 125

Why other options won't work:

A) 50(1.5) + 60(.75) = 75 + 12 [$87 is less than $125]

B) 60(1.5) + 40(.75) = 90 + 30 [$120 is less than $125]

C) 100 cupcakes + 30 cookies exceeds 120 treats
