Question

Over the last 3 months, Janet exercised a total of 101 hours. She exercised 4 hours more during the second month than the first month. In the third month, she exercised 3 hours less than the second month.

Create an equation that represents this situation, where h represents the number of hours Janet exercised during the first month.

Answer 1

In 1st month let she exercised h hours

in second month she exercised h+4 hours

in third month she exercised h+4-3=h+1 hours

Now

• h+h+4+h+1=101
• 3h+5=101
• 3h=96
• h=32hours

Answer 2

Let's say the unknown variable is h

In 1st month let she exercised h hours

in the 2nd month she exercised h+4 hours

in the 3rd month she exercised h+4-3=h+1 hours

Now, to display the sequence:

h+h+4+h+1=101

3h+5=101

3h=96

h=32hours
