Step-by-step explanation:
<u>Step 1: Define</u>
P = 2L + 2W
<u>Step 2: Solve for </u><em><u>L</u></em>
- Subtract 2W on both sides: P - 2W = 2L
- Divide 2 on both sides: (P - 2W)/2 = L
- Distribute division: P/2 - W = L
- Rewrite: L = P/2 - W
The answer to the question
Answer: $(d-3c)
Step-by-step explanation:
Total amount Tina had = $d
Cost of cupcakes = $c
Number of cupcakes purchased = 3
Therefore,
Total cost of cupcakes = cost per cupcake × number of cupcakes
Total cost of cupcakes = $c × 3 = $3c
Amount left after cupcake purchase:
Total amount Tina had - total cost of cupcakes :
$d - $3c
Answer:
