Question

Byron has 72 coins in his piggy bank. The piggy bank contains only dimes

Answer 1

Answer:

(3) $0.25q+0.10(72-q)=14.70$

Step-by-step explanation:

Let d represent number of dimes and q represent number of quarters.

We have been given that Byron has 72 coins in his piggy bank. We can represent this information in an equation as:

$q+d=72...(1)$

We are also told that the value of all coins is $14.70.

Value of d dimes: $0.10d$.

Value of q quarters: $0.25q$.

$0.25q+0.10d=14.70...(2)$

From equation (1), we will get:

$d=72-q$

Substitute this value in equation (2):

$0.25q+0.10(72-q)=14.70$

Therefore, the equation $0.25q+0.10(72-q)=14.70$ can be used to determine q, the number of quarters.
