Answer: He needs 80 cups.
Step-by-step explanation:$12/$.15=80 cups
Hey the first thing you do is reduce the numerator which is 648 to do that you have to mutiply the denominator by the factors 10,5,2,1. and then the partial quotient will add up as 50+20+10+1=81 :)
X = 1st evening, y = 2nd evening, z = 3rd evening
x + y + z = 83
x = z + 7
y = 2z
z + 7 + 2z + z = 83
4z + 7 = 83
4z = 83 - 7
4z = 76
z = 76/4
z = 19 <=== 3rd evening calls
x = z + 7
x = 19 + 7
x = 26 <=== 1st evening calls
y = 2z
y = 2(19)
y = 38 <=== 2nd evening calls
