Question

If the total budget of lighting is $\$$45.25 and the cost of wiring required is $\$$28, calculate the number of bulbs that can be purchased.

Cost of bulb = $\$$0.5/piece

• A. 32
• B. 33
• C. 34
• D. 35

Answer 1

The correct option is D 35

Given:
Cost of bulb = $\$$0.5/piece
Cost of wiring = $\$$28
Total budget = $\$$45.5
Amount left for the bulbs = 45.5 - 28
= $\$$17.5

Number of bulbs that can be purchased
= $\frac{\text{Amount left}}{\text{Cost of 1 bulb}}$

= $\frac{17.5}{0.5}$

= 35 bulbs
