Answer:
$58.5 (profit)
Explanation:
Ariana bought 5 dozen pears at $36 per dozen.
The value of 1 dozen = $ 36
Her buying amount = $36 * 5 = $180
The value of 1 pear = $ 36/12
= $3
The value of 7 pears= $3 * 7 = $21
She sold the remaining (53) at $4.50 each.
Her, selling amount = $4.50 * 53
= $238.50
Her profit amount = selling amount - buying amount
= $238.50 - $180
= $58.5
