Question

A blue whale gains 2.3 tons a month for the first year of life. If a blue whale weighed 15 tons at birth, how much will it weigh at 6 months of age?

Answer 1

It will weigh 28.8 tons in the first 6 months.

2.3 tons per month times 6 months equals 13.8 tons plus 15 tons equals 28.8 tons.

Hope this helps. ;)
