Question

Jan has $130. If she saves $25 per week, in how many weeks will she have $600?

Answer 1

Let's represent the number of weeks with the variable 'w':

130 + 25w = 600

We subtract both sides by 130:

25w = 470

w = 18.8

We round up:

It will take her 19 weeks.

Answer 2

Answer:

Jan got 19 weeks.

Step-by-step explanation:

The number of weeks should be the variable of "w."

$\displaystyle 130+25w=600$

Subtract by 130 from both sides of equation.

$\displaystyle 130+25w-130=600-130$

Solve.

$\displaystyle600-130=470$

$\displaystyle 25w=470$

Divide 25 both sides.

$\displaystyle\frac{25w}{25}=\frac{470}{25}$

Simplify, to find the answer.

$\displaystyle \frac{94}{5}=18.8=19$

There are 19 weeks.
