A.) A paint store sells exterior for $35.75 a gallon and paint rollers for $6.00 each. Write an equation in standard form for the number of gallons p of paint rollers r that a customer could buy with $190.

B.) Use your equation to determine the number of gallons of paint needed if a customer bought 6 rollers


Sagot :

The total price for the gallons of paint will be 35.75p

The total price for the rollers will be 6r

So the equation if the customer have 190 will be

price for gallons of paint + price for rollers = 190

35.75p + 6r = 190

(This is the equation)
