  3. 5. Marvin has $12, and every week he spends $24, but every 2 weeks Marvin's mom gives him a $60 allowance. If Marvin ever goes into debt his mom helps him pay, but that money counts in his $60 allowance. This continues for 18 weeks. The next week, Marvin's mom tells him if he cleans the whole house, she will give him 7 times the money he already has, but won't give the standard money, and Marvin can't spend any money that week. Marvin obviously agrees. The next 2 weeks, Marvin spends $44, instead of the normal $24, and his mom still gives the same 60. How much money does Marvin have?
