trisha standford earns $300 a week plus a 15% commission only on sales she makes after her first $1,000 in sales if ms standfords sales for one week are $2,500 what is her gross pay for that week

Answers

Answer:

Her gross pay for that week=$525

Step-by-step explanation:

Step 1: Express the gross pay

The gross pay can be expressed as follows;

A=F+(R×T)

where;

A=the gross pay per week

F=fixed income per week

R=commission rate

T=total commission sales

In our case;

F=$300 a week

R=15%=15/100=0.15

T=(2,500-1,000)=$1,500

replacing;

A=300+(15% of 1,500)

A=300+(0.15×1,500)

A=300+225=525

A=$525

Her gross pay for that week=$525

Which input value produces the same output value for the two functions on the graph?A.) x = -3
B.) x = -2
C.) x = -1
D.) x = 3

Answers

For the question "Which input value produces the same output value for the two functions on the graph?" The solution of a system of equations is the point at which both the input value and the output value of the equations have the same value. Graphically, it is the point of intersection of the graphs representing the equations. Here the point of intersection of the line representing the graph is point (-2, 1) with an x-value of -2 and a y-value of 1. The input value of a function is the x-value of the function. Therefore, the input value that produces the same output value for the two functions on the graph is -2.

Answer:

The right answer is x= -2
