Question

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?

Answer 1

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

Answer 2

A) r + b = 10
B) 4r + 3b = 37

-3r -3b = -30
4r + 3b = 37
r = 7
b = 3

7 roller coaster rides = 7*4 = 28 tickets
3 boat rides = 3 * 3 = 9 tickets
37 ticket total
