Answer:
8.4 weeks
Step-by-step 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
Answer: It will take you 9 weeks to have enough money to buy the bicycle.
Step-by-step 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.
