Question

Hi guys.

'Eric earns £14 per hour. He works for 38 hours per week. He saves 1/4 of his earnings
each week. How many weeks will it take him to save £1200?'

I believe I have the answer but I just want to check it is right as it is big test revision

Answer 1

It will take him around 9.02255 weeks. you multiple the amount he is getting by the hours. 14(38hrs) which is £532. he saves 1/4 so you divide 532 by 4 and get £133. After you divide £1200 by £133 which is 9.0225 so basically 10 weeks

Answer 2

It will take Eric 10 weeks to save £1200

Explanation:

He makes £14 per hour, since he works for 38 hours per week,

That means that he makes (14)(38) = £532 per week

Since he saves 1/4 of his earnings, that gives us,

Savings per week = (1/4)(weekly earnings)

Savings per week = 1/4(532)

Savings per week = £133 (per week)

Now, we need to find the number of weeks till he saves £1200,

we have,

Total savings = (number of weeks)(Savings per week)

let n = number of weeks,

Total savings = n(Savings per week)

so,

1200 = n(133)

n = 1200/133

n = 9.0225

Now, since he will have less than 1200 in 9 weeks (the number is greater than 9 i.e 9.0225 > 9)

So, we round up to 10,

Hence it will take Eric 10 weeks to save £1200
