Number of dimes is = 2 times the number of quarters, = 2 * n
amount A = n * $ 0.25 + 2 * n * $ 0.10
= $ 0.45 * n
Amount = $ 0. 45 * 12 = $ 5.40
amount A = n * $ 0.25 + 2 * n * $ 0.10
= $ 0.45 * n
Amount = $ 0. 45 * 12 = $ 5.40

Given a box contains some quarters and some dimes in the ratio 1:2
Now A.T.Q
1.
Number of dimes = 2n
Amount = n × $ 0.25 + 2 × n × $ 0.10
= $ 0.45 × n
2.
Amount = $ 0. 45 × 12 = $ 5.40
Now A.T.Q
