Question

John is saving 2/3 of his allowance each week for a wireless headset that he wants to buy. After 6 weeks he has $87 saved for the headset.

John's weekly allowance is ____.
Each week John saves _____ for the wireless headset he wants to buy.

Answer 1

John's weekly allowance is $21.75.

Each week John saves $14.5 for the wireless headset he wants to buy.

Step-by-step explanation:

87 / 6 = 14.5 he saved 14.5 dollars per week.

14.5/2 = 7.25 * 3 = 21.75

I divided by 2 to find the dollar per part, then muti by 3 to find all of the totals of the parts.
