Question

George weighed 160 pounds when he started college. If he gains just 0.25 pounds each month for four years of college, how much will he weigh? Suppose he doesn't change his habits after graduation, and continues that modest sounding waking weight gain for the next 10 years after college. How much will he weigh for his 10 college reunion?

Answer 1

George will weigh 172 pounds after four years of college, gaining 0.25 pounds per month. If he continues this trend for 10 more years, he will weigh 202 pounds at his 10-year college reunion.

Step-by-step explanation:

To calculate the weight gain of George after college and for the next 10 years, we can use simple arithmetic. George starts at 160 pounds and gains 0.25 pounds each month.

Weight After College

Four years of college is equivalent to 4 years × 12 months/year = 48 months. If he gains 0.25 pounds each month, then over 48 months he will have gained:

0.25 pounds/month × 48 months = 12 pounds.

So, after college, his weight will be:

160 pounds + 12 pounds = 172 pounds.

Weight After Next 10 Years

To calculate his weight after the next 10 years, which is 10 years × 12 months/year = 120 additional months, we do the following calculation:

0.25 pounds/month × 120 months = 30 pounds gain.

Adding this to his weight after college:

172 pounds + 30 pounds = 202 pounds.

Therefore, for his 10-year college reunion, George will weigh 202 pounds.

Answer 2

George will weigh 172 pounds after 4 years of college.

George will weigh 202 pounds 10 years after college.

Step-by-step explanation:

Given:

Weight at the start of the college = 160 pounds.

Weight gain per month = 0.25 pounds

We need to find the weight after 4 years college.

Also we need to find weight 10 years after college.

Solution:

Now we know that;

1 year = 12 months

4 years =
`12*4 = 48 \ months`

Number of months in 4 year of college = 48 months

Now we can say that;

weight after 4 years college can be calculated by sum of Weight at the start of the college and Weight gain per month multiplied by Number of months in 4 year of college.

framing in equation form we get;

weight after 4 years college =
`160+0.25*48 = 172 \ pounds`

Hence George will weigh 172 pounds after 4 years of college.

Now we need to find weight 10 years after college.

Now we know that;

1 year = 12 months

10 years =
`10*12 =120 \ months`

Number of months in 10 year after college = 120 months

weight 10 years after college can be calculated by sum of weight after 4 years college and Weight gain per month multiplied by Number of months in 10 year after college.

framing in equation form we get;

weight 10 years after college =
`172+0.25*120 = 202 \ pounds`

Hence George will weigh 202 pounds 10 years after college.
