Answer:
106 pizzas 
Explanation:
The number of more pizzas required to sell for earning $750 is as follows:
Given that
Already earned amount = $182.90 =x 
Need to achieved = $750 = y
So, the remaining amount would be 
= y - x
= $750 - $182.90
= $567.10
For every pizza sold, it make for $5.35
 So, the number of pizza would be 
= $567.10 ÷ $5.35
= 106 pizzas
