Carlos is mailing packages. Each small package costs him $2.40 to send. Each large package costs him $2.90. How much will it cost him to send 1 small package and 3 large packages?

$11.10

Step-by-step explanation:

1 small package = $2.40

1 large package = $2.90

1 small package + 3 large packages.

2.40 + (3 × 2.90)

=2.40 + 8.70

=11.1

$11.10

Step-by-step explanation:

This problem can be modeled by 2.4x+2.9y=c

x=small packages

y=large packages

c=total cost

By plugging in the values you get 2.4(1)+2.9(3)=c

2.4+8.7=c

c=11.1

Therefore the total cost is $11.10

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.

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.
