I think it’s B because the total he could spend is 52.50, so it could be less than that or equal to that very amount. The passage directly says he spent 31.75 on a coat. The only thing it didn’t give you a clear number on was the shirts, but it gives you the price so you put the price and the variable “s” together because you don’t know have many shirt he got.
Irrational as 0.75 x 0.75 x 3.14......

Hello.
In order to solve a proportion, you should cross-multiply:

Multiply 7 times 9 and 5 times x:
5x=63
Divide both sides by 5:
x=
Now let's solve the second proportion.
Multiply 8p times 6 and 12 times 15:
48p=180
Divide both sides by 48:
p=3.75
I hope it helps.
Have an outstanding day.

Answer:
MON= 57
Step-by-step explanation:
5x-23+3x-15=90
8x-38=90
8x=128
x=16
PLUG 16 INTO MON EQUATION
5(16)-23=57
therefore,
MON=57
USE COMPLEMENTARY FOR PROBLEMS LIKE THIS :)))
(btw, assuming that the angle is 90 degrees)
