Question

The cost of one food packet is ₹ 45 with a fixed delivery charge of ₹ 10. The total cost of $y$ food packets is given by ___.

• A. ₹ (45 + 10y)
• B. ₹ (45 + 10 + y)
• C. ₹ (45y + 10)
• D. ₹ (45 - 10y)

Answer 1

The correct option is C

₹ (45y + 10)

Cost of y food packets = cost of 1 food packet $\times$ number of food packets

$\Rightarrow$ Cost of y food packets = 45 $\times$ y

Total cost = cost for y food packets + fixed delivery charge

$\therefore$ Total cost = ₹ (45y + 10)
