1 quarter = 25 cents = $0.25

Hence, the number of quarters in $4.50

Converting $4.50 to cents

$1 = 100 cent

$4.50 = (4.50 * 100)

$4.50 = 450 cents

Number of Quarters in $4.50 :

450 cents / 25 cents

= 18 quarters

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
