raymond has $50.he spent 9.25 per comic book including tax on three comics. he needs to save $12.00 for admission to the next comic book fest. if plastic book covers are 1.15 each what is the maximum number of plastic book covers he can buy?
greater than 8
at most 8
at least 8
less than 8

I just took a test about this it’s at least 8

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
