A ride on the roller coaster costs 4 tickets while the boat ride only costs 3 tickets. Michael went on the two rides a total of 10 times and spent a total of 37 tickets which equation is true?
c is coasters and b are boat rides
4c + 3b = 37
c + b =10
c = 10- b, substitute into the first equatiom
4 (10- b) + 3b = 37
40 - 4b + 3b= 37
40 -b= 37
-b = -3
b= 3
now substitute into second equatiom
c+ 3 = 10
c = 7
