Question

GIVE OUT BRAINLY 2) Kathleen is a sales associate in a jewelry store. She earns $560/wk plus an 8% commission on sales. How much does she need to sell in a week to earn at least $700 that week?
a. Write an inequality equation to solve the problem. Use your choice of variable.


b. How much does she need to sell to earn at least $700 that week?


c. Graph the solution on a number line.

Answers:

Answer 1

700<=560+0.08x

x is total sales $

the 560 is the constant weekly pay, since we're only calculating for one week.

we're adding 0.08x to account for the 8% of the total sales

solve it for x:

700-560 <= 0.08x

140 <= 0.08x

1750 <= x

or x >= 1750

meaning she needs $1750 worth of sales that week to earn atleast $700

as for C) just draw a number line with the number 1750 in the middle and the right shaded because it is 1750 or more.
