Answer:

$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

Answer:

$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

Fill in the table using this function rule y=5x-3
Rudiy27

Answer:

-2, -13

0, -3

2, 7

4, 17

Step-by-step explanation:

To fill out the table, substitute the table x-values into the equation and the y-values will fill the table.

y = 5x - 3

y = 5(-2) - 3

y = -10 - 3

y = -13

This means the table value corresponding to -2 should be -13.

y = 5x - 3

y = 5(0) - 3

y = 0 - 3

y = -3

This means the table value corresponding to 0 should be -3.

y = 5x - 3

y = 5(2) - 3

y = 10 - 3

y = 7

This means the table value corresponding to 2 should be 7.

y = 5x - 3

y = 5(4) - 3

y = 20 - 3

y = 17

This means the table value corresponding to 4 should be 17.
