Question

A business has 4 humidifiers. The cost (in dollars) to buy and maintain the humidifiers for
`n` weeks is represented by
`520+32n` . Write an expression that represents the cost to buy and maintain one humidifier for
`n` weeks

Answer 1

130+8n

Explanation:

We know that all four humidifiers cost $520 to buy at first. So, we divide that by four to get the cost of one humidifer. $130.

We know that it costs $32 a week to keep all four humidifiers maintained. So, we divide that by four to get the cost of keeping one humidifier maintained. $8 per week.

130+8n is the equation that represents the cost of buying and maintaining one humidifier.
