Answer 4

Matt is saving for college. He puts $20 in his savings account each week. How many weeks, w, will it take for him to save $15000?

Answer 5

Let w be the number of weeks it takes for Matt to save $15000.
Matt saves $20 per week, so in w weeks, he will have saved 20w dollars.
We want to find w such that 20w = $15000.
Dividing both sides of the equation by 20, we have w = $15000 / $20 = 750.
Answer: \boxed{750}.

Answer 6

A cell phone company charges a shipping fee of 7% of the purchase cost, p. If the total cost of shipping is calculated to be $30.25, what is the purchase price before shipping was added?

Answer 7

Let p be the purchase cost before shipping is added.
The shipping fee is 7% of the purchase cost, so it is 0.07p.
We are told that the shipping fee is $30.25, so 0.07p = $30.25.
Dividing both sides of the equation by 0.07, we have p = $30.25 / 0.07 = $<<30.25/0.07=432.14>>432.14.
Answer: \boxed{432.14}.
