A customer service clerk earns $400 plus two thirds of their sales. What dollar amount of sales do they need this week to earn $2400. 1200

range is infinite on both x and y axis positive and negative

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

3+3+3+2*2*2+29*12 = 365
