Tom weighed 110 pounds at the beginning of the year. By June, he had gained 13 pounds, but in August he lost 5. How much did he weigh at the end of the year if he gained 4 more pounds during the month of November?
We know he started with 110 then gained 13. So 110 + 13 = 123. Next, he lost 5 pounds, 118 pounds. Once lost he gained another 4 pounds. The total weight that Tom weighed at the end of the year would be 122 pounds.
