Rebekah bought g gallons of paint for $12.85 per gallon and b brushes for $4.79 each. which expression can be used to determine the toatl amount of rebekah spent on paint and brushes?

12.85g+ 4.79b

Step-by-step explanation:

Given,

The cost of paint = $12.85 per gallon,

Number of gallon of paint = g,

So, the total cost of the paint = 12.85g dollars,

Also, the cost of brush = $ 4.79 per gallon,

Number of brushes = b,

So, the total cost of the brushes = 4.79b dollars,

Thus, the total cost = total cost of the paint + total cost of brushes

= 12.85g + 4.79b

Which is the required expression.

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.
