Equation 25−3.99p
represents the amount of money itzel has left over after buying p
bottles of nail polish.

what does the constant 25
represent in this context?

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

Step-by-step explanation:

Given:

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

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 .

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

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