You have total coins for a total of $. . You only have quarters and dimes. Let represent the number of quarters and represent th
Sonja [21]

Answer:

Quarters = 41

Dimes = 18

Step-by-step explanation:

Given

Coins = 59

Worth = \$12.05

d = dimes

q = quarters

Required

The number of each coin

The total coins can be represented as:

d + q = 59

1\ quarter = \$0.25 \\ 1\ dime = \$0.10

So, the worth of the coin is:

0.25q + 0.10d = 12.05

The equations to solve are:

0.25q + 0.10d = 12.05

d + q = 59

Make d the subject in: d + q = 59

d =59 - q

Substitute d =59 - q in 0.25q + 0.10d = 12.05

0.25q + 0.10(59 - q) = 12.05

0.25q + 5.9 - 0.10q = 12.05

Collect like terms

0.25q  - 0.10q = 12.05 - 5.9

0.15q = 6.15

Solve for q

q=\frac{6.15}{0.15}

q=41

Substitute q=41 in d =59 - q

d = 59 - 41

d = 18

So:

Quarters = 41

Dimes = 18
