<PRE><B>Question 1189425</B>
The school dance team wants to raise money to purchase Custom made t-shirts and warm-up pants to wear before Competitions. 
The team decides to sell boxes of cookies for $2.50 each. 
 For each of the first 100 boxes sold, the team will receive $0.60.
 For each of the next 200 sold, the team will receive $0.75.
 For each additional box of cookies sold, the team will receive $0.95.
 How many boxes must the team sell in order to reach its goal of raising
$400.00?
:
1st 100 boxes: (100*.60) = $60
Next 200 boxes: (200*.75) = $150
The 1st 300 boxes earn $210. 
Therefore we need; 400-210 = $190 more. 
Find the no. additional boxes (x) to earn $190 more to equal a total of $400
.95x = 190
x = 190/.95
x = 200 more boxes
300 + 200 = 500 boxes to earn $400</PRE>
