5x = 2x-15
3x = -15
x = -5

substitute x = -5 into one of your equations
so y = 5x becomes y = 5 x -5
y= -25

x=-5 and y=-25

Allison is offered an annual salary of $24,500. What would be her biweekly gross pay? (Round to the nearest cent.) A. $2,041.67
bixtya [17]

Answer:

Option (B) is correct.

Allison biweekly gross pay is $942.31

Step-by-step explanation:

Given annual salary offered to Allison  = $24,500.

We have to calculate Allison biweekly pay that is pay Allison got for 2 weeks

To calculate biweekly we first find Allison weekly pay then multiply it by 2.

We know there are 52 weeks in a year.

So, weekly salary offered to Allison =\frac{24500}{52}=471.15(approx)

Biweekly salary will be = 2 × weekly salary

                                      = 2  × 471.15

                                       = 942.307(approx)

Thus, Allison biweekly gross pay is $942.31
