Kimuyen needs to earn $4,150 per month in order to pay all her expenses. her job pays her $3,475 per month plus a commission of 4% of her total sales. what is the minimum kimuyen's total sales must be in order for her to pay all her expenses?

The minimum sales should be $16,875.

Step-by-step explanation:

Consider the provided information.

Her job pays her $3,475 per month plus a commission of 4% of her total sales.

Let the total sales is x.

Thus the amount Kimuyen earn

Kimuyen needs to earn $4,150 per month in order to pay all her expenses.

Therefore, Kimuyen can earn more than 4150 but not less than it.

Hence, the minimum sales should be $16,875.

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
