Question

Three students each received a weekly allowance. They each spent some and donated the remainder to their classroom charity. Who donated the most?

Weekly
Allowance Number of
Weeks Saved Amount
Spent
Sheila $5 3 $9
Mario $4 4 $8
Gina $6 4 $17

Answer 1

Mario

Explanation:

Sheila has a 5 dollar allowance and saved for 3 weeks. 3 x 5 = 15 dollars saved total. She spends 9 of the 15. 15 - 9 = 6, so Sheila donated 6 dollars.

Mario has a 4 dollar allowance and saves for 4 week. 4 x 4 is 16 dollars saved. He then spends 8 of them, 16 - 8 = 8 dollars donated.

Gina has a 6 dollar allowance and saves for 4 weeks. 6 x 4 is 24. She then spends 17 dollars. 24 - 17 is 7 dollars donated.

Sheila donates 6 dollars. Mario donates 8 dollars. Gina donates 7 dollars.
Out of the three, Mario has donated the most.
