A = 5/6B
A = 150.60
150.60 = 5/6B
150.60 / (5/6) = B
150.60 * 6/5 = B
903.60/5 = B
180.72 = B
180.72 - 150.60 = 30.12....u save 30.12 when buying from store A

Step-by-step explanation:
All you have to do is divide the base/width by area.
Do you have a picture? I don’t know what information is given
R/ r+ 15 = 3/8
Cross multiply: top of one side multiplied by bottom of other side:
R x 8 = 3 x r+ 15
Simplify:
8r = 3r + 45
Subtract 3r from both sides:
5r = 45
Divide both sides by 5:
R = 9
