Sam borrowed 50 dollars. Since 4.50 is 9% and 9% is so close to 10% I rounded up to 5 is 10% as a guess. Doing this, I multiplied both by ten to get 50=100%. To check, I multiplied 50 by .09 (9%) and got 4.5

A phone company offers two monthly plans. Plan A costs $16
Trava [24]
We can write two equations for this. x = each minute of calls

Plan A = .1x + 16
Plan B = .14x

Make the two equations equal each other, so we can find when they are the same.

.1x + 16 = .14x

Subtract .1x from both sides

16 = 0.04x

Divide by 0.04 to get x by itself

400 = x.

Earlier, we set x as each minute of calls. This means that after 400 calls, Plan A and Plan B will cost the same.

To find the cost, substitute 400 into both equations by themselves.

Plan A cost = .1x + 16
Plan A cost = .1(400) + 16
Plan A cost = 40 + 16
Plan A cost = $56

Plan B cost = .14x
Plan B cost = .14(400)
Plan B cost =  $56

Final answer: After 400 calls, Plan A and Plan B will both cost $56.
