Lilit [14]3 years ago
8 0

Answer:

Step-by-step explanation:

$ 4 per ride and 0.75 per mile

y = 0.75x + 4.....with x being # of miles and y being total cost

if a person only had $ 20....so sub in 20 for y and solve for x

20 = 0.75x + 4

20 - 4 = 0.75x

16 = 0.75x

16 / 0.75 = x

x = 21.33 (or 21 1/3) miles <=====

Hello There!

First work out the number of shelves per bookcase:
65/13 = 5
It is 5 shelves per bookcase.
6 x 5 = 30.
Therefore 32 shelves are enough to make 6 bookcases.

Hope This Helps You!
Good Luck :)
