Answer:
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.
