Andrew Dean · 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

Johns · 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
