Question

Eric 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. In the equation y = 4x − 110, which is the constant term?

a.y
b.4
c.x
d.−110

Answer 1

d. -100

because a constant never changes

Answer 2

Option d = -110

Explanation:

Given : Eric 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.

To find : Which is the constant term?

Solution :

The cost of the Eric shirt sell is $100+$10=$110

Eric sells each shirt for $4.

x be the number of shirt sell and y is the total cost of the shirt.

The equation he uses is
`y = 4x-110`

In this equation, y is dependent on x and x is an independent variable.

4 is the coefficient of x and -110 is the constant term as its is not dependent on anything.

Therefore, Option d is correct.

The constant term in the equation is -110.
