Pears cost 0.92 per pound and apples cost 1.10 per pound. mr bonilla bought 3.75 punds of pears and 2.1 pounds of apples. how much did he pay for the pears and apples?

Let

x> the number of pounds of pears

y> the number of pounds of apples

z> the total cost

we know that

z=0.92*x+1.10*y> equation 1

x=3.75 lb> equation 2

y=2.1 lb > equation 3

Find the total cost

Substitute equation 2 and equation 3 in equation 1

z=0.92*(3.75)+1.10*(2.1)> z=3.45+2.31> z=$5.76

therefore

the answer is

$5.76

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
