Question 1201018
<br>
A quick informal solution method....<br>
If all 150 boxes were standard, the cost would have been $450.
The actual total cost was $645, which is $195 more.
The difference in price between the two kinds of boxes is $3.
So the number of deluxe boxes sold was 195/3 = 65.<br>
ANSWER: 65 deluxe boxes; 150-65 = 85 standard boxes<br>
