You spend 1/2 of your allowance each week on lunches. each lunch is $1.25. how much is your weekly allowance?

Question

please help me. you need to write an equation to solve the problem. i start school tomorrow. thank you.

Answer 1

Assuming you buy your lunch five days a week, you spend $6.25 a week on lunches.  If tha't half your allowance, then your allowance must be $12.50 ($6.25 x 2) a week.  

Answer 2

Well, if each lunch is $1.25 and there are 7 days in a week (or 5 if it is only for school)...then you find out how much you are spending a week for lunch. And if that is half your allowance, then you need to double it, which will give you your total allowance for the week!

Answer 3

if its lunch 7 days a week. then $17.50 per week for allowance.

Answer 4

(1.25 x 5) x 2 = $12.50  (5 day week)

(1.25 x 7) x 2 = $17.50  (7 day week)
