4.2
Step-by-step explanation:
Joyce and Tina had an equal amount of money
Lets x = # of days they spent money
Joyce spent $24 still had $64 left = 24x + 64
Tina spent $28 a day and spent all her money, no left = 28x

4x = 64
Divide both sides by 4
x = 16

variables d and w
5d +1(4d)=36
9d=36
d=4 w=4x4=16
difference of price $12
5)
E 5 comics
F= 10
G=20
e+ (e+5) + 2(e+5)=35
e+ e+5 + 2e +10 =35
4e +15=35
4e=20
e=5
Eugene = 5 comics
