Answer:
Rancho Turbo gets 23 mpg & Supra gets 18 mpg
Explanation:
Let mpg of Rancho Rurbo be r and mpg of Supra be s
We can write equations as:
r = s + 5
and
s + 2r = 64
We can substitute 1st equation into 2nd and find s first:
s + 2(s+5) = 64
s + 2s + 10 = 64
3s = 64 - 10
3s = 54
s = 54/3
s = 18
Thus, r = s + 5 = 18 + 5 = 23
Rancho Turbo gets 23 mpg & Supra gets 18 mpg
