Ric sells shirts. it costs him $100 to buy all the shirts and $10, total, to print designs on them. eric sells each shirt for $4. so far he has sold 20 shirts. he uses the equation y = 4x - 110 to calculate his profit.

what is the constant in eric’s equation?
a) 4
b) -10
c) 20
d) -110

First, you'll want to identify the given in the problem.

It costs 100 dollars to purchase all of the shirts and 10 dollars to print the designs on the shirts. The result being a 110 dolar investment prior to his sales. In addition, each shirt is sold for 4 dollars and this becomes the slope of the equation.

Using this info the following equation can be used to find Eric's profit:

P=4x-110

With 4 being the slope.

Overall, after selling the 20 shirts by plugging 20 in for x we get 80-110. So his profit is -30 dollars.

Hope this helps :)

Ithink you're supposed to multiply 12.50 which is how much he makes per hour and then multiply it by each number then add whats left togrther and there's your answer

The operation is suck a c@ck? !
