Leila is saving money to buy a bike that costs
$
125

. she has
$
60

and will save an additional
$
5

each week. in how many weeks will she have enough money to buy the bike?
write an equation, let w represent the number of weeks

Equation: 5w + 60 = 125

13 weeks

Step-by-step explanation:

Cost of bike: $125.

She has: $60.

(money she has) + (all money saved weekly) = (cost of bike)

60 + (all money saved weekly) = 125

In 1 week she saves $5.

In 2 weeks, she saves $5 * 2

In 3 weeks, she saves $5 * 3

In w weeks, she saves $5 * w = 5w.

"all money saved weekly" is 5w, so we put that in our equation.

60 + 5w = 125

Equation: 5w + 60 = 125

Now we solve the equation for w.

5w + 60 = 125

Subtract 60 from both sides.

5w = 65

Divide both sides by 5.

w = 13

13 weeks
