The amount of money spent buying packets of instant noodles varies directly with the number of packets purchased. If 30 packets of noodles cost $34.88, how much would 45 packets cost? Round all answers to the nearest hundredth in your calculations.

Question

$25.83

$43.00

$38.70

$52.20

Answer 1

To find out how much 45 packets of instant noodles would cost, we first need to determine the cost per packet of noodles based on the information given for 30 packets.

1. Calculate the cost per packet: \[ \text{Cost per packet} = \frac{\text{Total Cost}}{\text{Number of Packets}} = \frac{34.88}{30} \] \[ \text{Cost per packet} = 1.16266667 \approx 1.16 \text{ (rounded to the nearest hundredth)} \]

2. Calculate the cost for 45 packets: \[ \text{Cost for 45 packets} = \text{Cost per packet} \times \text{Number of Packets} = 1.16 \times 45 \] \[ \text{Cost for 45 packets} = 52.20 \]

So, the cost for 45 packets would be $52.20.
