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

We have to determine the constant in the equation, which shows how Eric can calculate his profit ( y ). He sells each shirt for $4 and he has total expenses: $100 + $10 = $110. So the equation for profit is: y = 4 x - 100. In this equation y is dependent variable, x is independent variable, 4 is coefficient and - 100 is the constant. A constant is a number ( a quantity that does not vary ). D ) - 110.
