Answer:

$160

Step-by-step explanation:

Part A-

Step 1: 6(2k+5) - 20

Step 2: 6(2k) + 6(5) - 20

Step 3: 12k + 30 - 20

12k + 10

Part B-

12(12.50) + 10

150 + 10

$160

Answer:

A: 12k+30-20

B: $160

Step-by-step explanation:

A: You multiply all of the numbers that are in the parenthesis for distributive property (6x2k and 6x5) but you leave the numbers that are not inside the parenthesis (-20).

B: Once you get your equation from Part A, you just need to substitute k with $12.50.

12k+30-20

=12(12.50)+30-20

=150+30-20

=180-20

=160
