Answer:

$195

Explanation:

Step 1: Given data

  • Cost of a 1-gallon can of paint (cC): $13.69
  • Number of 1-gallon cans of paint (nC): 3
  • Cost of a paint brush (cB): $9.53
  • Number of paint brushes (nB): 2
  • Cost of a helper (cH): $135
  • Number of helpers (nH): 1

Step 2: Calculate the total estimated cost for remodelling the interior of an apartment

We will use the following expression.

C = cC × nC + cB × nB + cH × nH

C = $13.69 × 3 + $9.53 × 2 + $135 × 1

C = $195
