Katie went to the convenience store to buy some snacks. She spent a total of $16.00 on soda and candy. The soda cost $4.00 and each candy bar cost $2.50. Write an equation that represents this problem.

4 + 2.5c = 16

Step-by-step explanation:

Let c = number of candy bars

All soda cost $4.00

Each candy bar costs $2.50, so c number of candy bars cost 2.5c.

The total cost is the sum of the costs of the soda and candy bars.

Total cost is 4 + 2.5c

To write the equation we set the total cost expression above equal to the given total cost.

4 + 2.5c = 16

lets t be the time, and w the weather.

The t, is dependent of the situation because as the time t, increases, also the earnings increase ($7 an hour)

The w, is independent of the situation because nothing is said about it, nothing like, she doesn't work if its cloudy, or gains more money if it is hot.
