Question

the equation 25-3.99p represents the amount of money itzel has left over after buying p bottles of nail polish. what does the coefficient 3.99 represent in this context

Answer 1

The coefficient 3.99 represent the cost of one bottle of nail polish.

Explanation:

Given:

The equation to represent the amount of money left after buying 'p' bottles of nail polish is given as:

`25-3.99p`

The remaining amount with Itzel can be calculated as:

Remaining amount = Initial amount - Cost of 'p' bottles.

The above expression tells us two things:

1. Initial amount of money Itzel has was 25.

2. The cost of 'p' bottles of nail polish is
`3.99p`.

Therefore, the cost of one bottle is calculated using the unitary method is given as:

`\textrm{Cost of 1 bottle}=\frac{\textrm{Cost of 'p' bottles}}{\textrm{Number of bottles}}\\\\\textrm{Cost of 1 bottle}=(3.99p)/(p)=3.99`

Therefore, cost of 1 bottle of nail polish is 3.99. Hence, coefficient 3.99 represent the cost of one bottle of nail polish.
