(2x + 10) + (6x + 1) = 180 - 79
Answer:
$320
Step-by-step explanation:
12 1/2% = 12.5%
12.5% = $40
1% = 40 ÷ 12.5 = $3.20
100% = $3.20 x 100 = $320
Answer: Caroline = 225
Step-by-step explanation:
Let Sarah be x
Caroline will be 3x
Bridget will be 2(3x) = 6x
x + 3x + 6x = 750
10x = 750
x = 750 / 10 = 75
Caroline gets 3x = 3 * 75 = 225
