Answer:
Dimes = 8 and
Quarters = 12
Step-by-step explanation:
Total value = 380 cents
let dimes be x
quarters be 2x - 4
100 pennies = $1
1 dime = 10 pennies
1 quarter = 25 pennies
Therefore;
$ 3.78 = 378 pennies
10x+25(2x-4)=378
10x + 50 x - 100 = 378
60 x = 378 + 100
60 x = 478
x = 478/60
= 7.9667
≈ 8
Therefore;
Dimes = 8 and
Quarters = 12
