Answer:
28.5 square boxes
Step-by-step explanation:
separate it into a rectangle and a triangle
then the area of rectangel = 8 * 3 = 24
area of triangle = 1/2 * 3 * 3 = 4.5
total area = 28.5 square boxes
check what is the area for each box
color : 40p + 50f + 90
b&w : 15p+20f + 45
p = 26
f = 45
[substitute the values given]
color : 40(26) + 50(45) + 90
b&w : 15(26)+20(45) + 45
[solve the equation]
color : 3380
b&w : 1335
[subtract to see how much ink is saved]
3380 - 1335 = <u>2045</u>
Answer:
10
12.5% less than 80 = 10
