Lynn has $8.58 in quarters and pennies. If she has eight times as many pennies as she does

Answer 1

I will assume your incomplete sentence would say:
"If she has eight times as many pennies as she does quarters, how many of each does she have ?"

number of quarters ---- x
number of pennies ---- 8x

value of coins equation:
25x + 8x = 858

solve for x and state your conclusion
