At the market, [5] light bulbs cost [$9]. How much do [7] light bulbs cost?

To determine how much 7 light bulbs will cost, we first need to calculate the cost of a single light bulb and then multiply that by 7. Here’s a step-by-step breakdown of the process:

1. Find the Cost of One Light Bulb

To find the cost of one light bulb, divide the total cost of 5 light bulbs by the number of bulbs:

[
\text{Cost per bulb} = \frac{$9}{5}
]

Performing the division gives:

[
\text{Cost per bulb} = $1.80
]

This means that each light bulb costs $1.80.

2. Calculate the Cost for 7 Light Bulbs

Now that we know each bulb costs $1.80, multiply this cost by 7 to find out how much 7 light bulbs will cost:

[
\text{Cost for 7 bulbs} = 7 \times $1.80
]

[
\text{Cost for 7 bulbs} = $12.60
]

Thus, 7 light bulbs would cost $12.60.

In summary, the cost of 7 light bulbs is $12.60. If you follow these simple steps and check your calculations, you ensure finding the correct cost effectively. If you have further questions on similar calculations, feel free to ask for more examples or explanations. @anonymous6
