Question

You are buying shirts for an organization. You have $120 to spend. The number of short-sleeved shirts y you buy after buying x long-sleeved shirts is y = -1.2x + 24

Answer 1

`x = 20` --- x intercept

`y = 24` --- y intercept

Explanation:

Given

`y = -1.2x + 24`

`Amount = \$120`

Required

Determine the intercepts

To find the x intercept;

Set
`y = 0`

This gives:

`0 = -1.2x + 24`

Collect Like Terms

`1.2x = 24`

Make x the subject

`x = (24)/(1.2)`

`x = 20`

To find the y intercept;

Set
`x= 0`

This gives:

`y = -1.2 * 0 + 24`

`y = 0 + 24`

`y = 24`
