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
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
