Answer:
Step-by-step explanation:
Given data
Profit from apple= $0.4
Profit from banana= $0.4
Let the number of Apples sold be x, and the number of bananas sold be y
and the total profit be P
Hence the expression for the total profit is given as
It's -18.
-1/6b=3
Multiply the reciprocal of -1/6 to both sides, this will get x by itself
(-6/1)*-1/6b=3*(-6/1)
b= -18/1
b= -18
Each book costs $15. since he had 18 dollars left, you can subtract 18 from 108. then divide that answer by 6. 90/6 = 15.
Hope that helped!
13. You add the 8 and the 5
10.2 x 2 = 20.40
9.4 x 3 = 28.20
Total= 48.60
