Ivana works at a department store selling perfume and makeup. She earns $375 per week and 4% commission on her sales. If Ivana's sales for the week were $2513, what are her total earnings for the week?

Step-by-step explanation:

Step one:

given data

weekly earnings= $375

Commission is 4% of sales.= 0.4

supposing sale is x, and the total earning is y

the expression for the total earning will be

y=375+0.4x

Step two:

for x= 2513, y will be

y=375+0.4(2513)

y=375+1005.2

y=1380.2

Hence  her total earnings for the week will be $1380.2

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
