Question

A collection of quarters, dimes, and nickels is worth $5.00. If the ratio of quarters to dimes to nickels is 2:4:7, how many quarters are there

Answer 1

Answer:

no. of quarter = 8

Step-by-step explanation:

1 quarter = 25 cents

1 dime = 10 cents

1 nickel. =. 5 cents

ratio = 2 : 4 : 7

amount worth = $ 5.00 = 500 cents

let x be the constant

2x (25) + 4x ( 10) + 7x ( 5) = 500

50x + 40 x + 35 x = 500

125 x = 500

x = 500 / 125

x = 4

No. of quarters = 2x

= 2 × 4

= 8
