Question

Melissa wants to buy a bike that costs $135. This is $25 more than 5 times what she saved last month. How much did she save last month? Define a variable, write an equation, and solve. Variable:​

Answer 1

Variable: x = amount she saved last month

Equation: 135 = 5x + 25

To solve:

135 = 5x + 25

135 - 25 = 5x

110 = 5x

`(110)/(5) = (5x)/(5)`

22 = x

To check:

135 = 5(22) + 25

135 = 110 + 25

135 = 135
