Answer:
$3450
Step-by-step explanation:
The cost of one computer is the sum of the cost of the parts:
$120 +100 +45 +30 +50 = $345
Then the cost of 10 of them is ...
10 × $345 = $3450 . . . . cost for 10 computers
Profit = paid - supplies
Plug in the given values. We are finding out how much money he needs per room, if he is doing 4 rooms, and subtracting the supplies: 300 = 4n - 4*32.50
Simplify: 300 = 4n - 130
Add 130 to each side. 430 = 4n
Divide by 4 on each side: 107.50= n
300 = 4(107.50) - 130? True
This tells us he must be paid $107.50 to make $300 exactly. Anything larger than $107.51 and up will make more than $300.
