Answer:

Step-by-step explanation:

Subtract equation 2 from equation 1

.7x+y-(-1.5x+y)=340-320

.7x+y+1.5x-y=20

2.2x=20

x=100/11, then use this in either original equation to find y.

.7(100/11)+y=340

y=3670/11, so the balance point is

(100/11, 3670/11)

mrs_skeptik [129]

Answer:

The amount of sales in order to cover his monthly expenses must be greater than or equal to $22,500

Step-by-step explanation:

Let

x----> represent the amount of sales Ollie will need

we know that

The amount of sales for the month multiplied by the commission rate as a decimal plus the fixed amount must be greater than or equal to $5,400 each month

so

The inequality that represent this situation is

0.12x+2,700\geq 5,400

solve for x

subtract 2,700 both sides

0.12x \geq 5,400-2,700

0.12x \geq 2,700

divide by 0.12 both sides

x \geq \$22,500

The amount of sales in order to cover his monthly expenses must be greater than or equal to $22,500
