Book a has 24 more pages than book b. book c has 4 times as many pages as book a. the total number of pages of pages of the three books is 180. how many pages does book b have?

A = 24 + b
c = 4a = 4(24 +b) = 96 + 4b
b =b
a + b + c = 180
24 + b + b + 96 + 4b = 180
Combine the variables and the whole numbers: 
120 + 6b = 180
-120           -120
6b = 60
divide on both sides by 6, and b=10
b = 10 a = 34 c = 136, 10 + 34 + 136 = 180

Do the math. she originally had 50 dollars on her gift card and she had 12 dollars left on her gift card after she finished her shopping spree. if you subtract 50 minus 12 you get thirty eight dollars as your answer. so therefore, ciara spent 38 dollars total o
