Answer 1

Answer:

Step-by-step explanation:

Given

$240 = 12x + 8y$

Required

Plot a graph

First, we need to determine the minimum and maximum values of x and y

For x:

Minimum = 0

For maximum; Let y = 0

$240 = 12x + 8y$

$240 = 12x + 8 * 0$

$240 = 12x$

Solve for x

$x = 240/12$

$x = 20$

For y:

Minimum = 0

For maximum; Let x = 0

$240 = 12x + 8y$

$240 = 12 * 0 + 8 * y$

$240 = 8y$

Solve for y

$x = 240/8$

$x = 30$
