Question

You are saving money to buy a new bicycle that costs $155.75. You have $30 and plan to save $5 each week. Your aunt decides to give you an additional $10 each week

Answer 1

Answer: It will take you 9 weeks to have enough money to buy the bicycle.

Explanation:

You are required to have $155.75 to be able to buy the bicycle. You already have $30 and plan to save $5 each week. Also, your aunt decides to give you $10 each week. So really, you’ll be saving up $15 each week since 10 + 5 = 15.

Next, multiply 15 by whichever number and see what you get. Make sure to add 30 to it, since you already have $30.

15 x 9 = 135, and that + 30 equals to 165. As you can see, you have enough money to buy the bicycle.

Therefore, it will take 9 weeks to be able to purchase the bike.

Answer 2

8.4 weeks

Explanation:

Linear equation Problem

given data

cost of bicycle= $155.75

money at hand= $30

savings per week=$5

tips per week=$10

therefore total savings per week= $15

We know that the expression for the total amount is

y=mx+c

therefore we can solve for the number of weeks it will take to arrive at the cost of the bicycle

155.75=15x+30

solve for x

155.75-30=15x

125.75=15x

x=125.75/15

x=8.4

therefore it will take up to 8.4 weeks to save up for the bicycle
