Answer:
$532.03
Step-by-step explanation:
Ann: 4 cameras + 2 computers = $2868.32
Sister: 2 cameras + 5 computers = $3562.28
If the sister has bought 2 sets:
Sister: 4 cameras + 10 computers = 3562.28 x 2 = $7124.56
Comparing the two equations:
4 cameras + 2 computers = $2868.32
4 cameras + 10 computers = $7124.56
We can conclude that:
10 - 2 computers = 7124.56 - 2868.32
8 computers = $4256.24
If 8 computers = $4256.24
1 computer = $4256.24 ÷ 8 = $532.03
