A hardware store sells 2 gallons of paint and a paintbrush for a total of $45. Last year, Katy bought 4 gallons of paint and a paintbrush in order to paint her porch and paid a total of $85. The system of equations below represents this relationship.
2x+y=45
4x+y=85
This year, Katy needs to paint a shed, so she buys more paint and paintbrushes. She replaces the equation 4x+y=85 with the equation 6x+2y=130, which is the sum of 4x+y=85 and 2x+y=45.
Determine whether each statement below is true. Select (Yes) or (No) for each statement.
The price of a paintbrush this year is $5.
The price of a gallon of paint thi year is $25.
The price of a paintbrush this year is the same as it was last year.
The price of a gallon of paint this year is the same as it was last year.
This year, Kelly buys 6 gallons of paint and 2 paintbrushes for $130.
