Jim has found a playstation that Jim Jim has found a PlayStation that costs $400 that he wants to buy. He received $150 dollars today as a gift from his family. How much money, in dollars, will he have saved 6 weeks from now if he earns $30 a week delivering pamphlets?

He has saved $330 and needs $70 to get the PlayStation

Step-by-step explanation:

The cost : $400

How much saved right now : $150

$400 - $150 = 250

He is earning $30 a week for 6 weeks

$30 x 6 = 180

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
