Steve puts only dimes and quarters into his piggy bank. Right now he has five more dimes than quarters there, and they make $74.35. How many quarters and how many dimes are there in Steve’s piggy bank?

Respuesta :

d= number of dimes
q= number of quarters
(Keep in mind, it's not the price, but the number of each)
0.1d+0.25q=74.35
d=q+5
0.1(q+5)+0.25q=74.35
0.35q+0.5=74.35
0.35q=73.85
q=211
d=216

Answer:

Step-by-step explanation:

d= number of dimes

q= number of quarters

(Keep in mind, it's not the price, but the number of each)

0.1d+0.25q=74.35

d=q+5

0.1(q+5)+0.25q=74.35

0.35q+0.5=74.35

0.35q=73.85

q=211

d=216
