You are ordering short-sleeve shirts (x) for $10 and long-sleeve shirts (y) for $15. Your budget is $300. Write the equation and find the intercepts.

Interpret their meaning.

Answer:

The x-intercept shows that you can buy 30 short-sleeve shirts and 0 long-sleeve shirts.

The y-intercept shows that you can buy 20 long-sleeve shirts and 0 short-sleeve shirts.

Step-by-step explanation:

Given

$10 per short sleeve

$15 per long sleeve

Budget = $300

The above can be represented as:

Total Cost of Short Sleeve + Total Cost of Long Sleeve = Budget

i.e.

$10 * x + 15 * y =300$

$10x + 15y =300$

To solve for the y intercept, we set x to 0

$10 * 0 + 15y =300$

$15y =300$

Divide through by 15

$y = 20$

<em>This implies that, you can buy 0 short sleeves and 20 long sleeves</em>

To solve for the x intercept, we set y to 0

$10x + 15 * 0 = 300$

$10x = 300$

Divide through by 10

$x = 30$

<em>This implies that, you can buy 0 long sleeves and 30 short sleeves</em>
