a student bought a juice pouch for 2.50 and 3 bags of chips. the total cost was 5.05. write and solve an equation to determine the cost of a bag of chips

1 answer

Let's define the cost of one bag of chips as \( x \).

According to the information provided, the student bought 1 juice pouch for $2.50 and 3 bags of chips. The total cost was $5.05.

We can write the equation for the total cost as follows:

\[ 2.50 + 3x = 5.05 \]

Now, let's solve for \( x \):

  1. Subtract $2.50 from both sides: \[ 3x = 5.05 - 2.50 \] \[ 3x = 2.55 \]

  2. Divide both sides by 3: \[ x = \frac{2.55}{3} \] \[ x = 0.85 \]

Thus, the cost of one bag of chips is $0.85.
