Answer
$16$ quarters.
Work Step by Step
$1$ quarter $=\$0.25$
Charges to wash one load of clothes $=\$2.25$.
Charges to dry one load of clothes $=\$1.75$.
Total cost to wash and dry one load of clothes.
$=\$2.25+\$1.75$
$=\$4$.
$\$0.25=1$ quarter
Multiply both sides by $16$.
$16\times \$0.25=16\times1$ quarter
Simplify.
$\$4=16$ quarters.
