{-1,7}
Step-by-step explanation:
1/2 | 5x-15| = 10
Multiply each side by 2
1/2 *2 | 5x-15| = 10*2
| 5x-15| = 20
Absolute value equations have two solutions, one positive and one negative
5x-15 = 20 5x-15 = -20
Add 15 to all sides
5x-15+15 = 20+15 5x-15 +15 = -20+15
5x= 35 5x=-5
Divide by 5
5x/5 = 35/5 5x/5 = -5/5
x=7 x=-1
$450.00 for 6 weeks
or
$300
step-by-step explanation:
$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.
$200 for first week
$200 x 0.10 = $20
$20 x 5 = $100
$200 + $100 = $300
