Question

The cost to join the Ski Club is $270. You pay a deposit of $95.50 and plan to save an additional $20 per week to pay for the cost. What equation will you use to find the number of weeks x you will need to save?

Answer 1

Answer:

a) The equation will you use to find the number of weeks x you will need to save is:

270 = 95.50 + 20x

b) The number of weeks x = 8.725 weeks

Step-by-step explanation:

Let:

The cost to join the Ski club = y

The number of weeks you will need to save = x

From the question, we have the following information:

The cost to join the Ski Club is $270. You pay a deposit of $95.50 and plan to save an additional $20 per week to pay for the cost.

The equation will you use to find the number of weeks x you will need to save is:

y = $95.50 + $20 × x

y = $270

Hence:

270 = 95.50 + 20x

Solving for x

270 = 95.50 + 20x

270 - 95.50 = 20x

174.5 = 20x

x = 174.5/20

x = 8.725 weeks

Hence, the number of weeks needed to save is 8.725 weeks
