Answer:
23 cupcakes
Step-by-step explanation:
Volume is the key to this question;
Calculate the volume of the cupcake;
3 × 3 × 3 = 27 inches^3
Then the volume of the box;
15 × 7 × 6 = 630 inches^3
Then divide the volume of the box by the volume of the cupcake to see how many can fit in;
630 ÷ 27 = 23.3333
;Hence you can fit... 23 cupcakes

40% of 15 is 6, and 15 + 6 is 21
x=-6
y=30
-5x =2x+42
y=2(-6)+42
=30.
11.25/375 = 0.03 which is 3%
