Tim spent \( \$3 \) on the pack of markers.

Solución

To solve the problem, we need to determine how much Tim spent on the pack of dry erase markers. 1. **Identify the known values:** - Total amount spent: \( T = 6 \) - Cost of each notebook: \( C_n = 3 \) - Number of notebooks: \( N = 3 \) 2. **Calculate the total cost of the notebooks:** \[ \text{Total cost of notebooks} = N \times C_n = 3 \times 3 = 9 \] 3. **Set up the equation for the total amount spent:** Let \( C_m \) be the cost of the pack of markers. The equation for the total amount spent is: \[ T = \text{Total cost of notebooks} + C_m \] Substituting the known values: \[ 6 = 9 + C_m \] 4. **Solve for \( C_m \):** \[ C_m = 6 - 9 = -3 \] Since the cost of the markers cannot be negative, it seems there is an inconsistency in the problem. Tim cannot spend \( \$6 \) on 3 notebooks that cost \( \$3 \) each, as that alone totals \( \$9 \). Thus, it appears that Tim's total spending of \( \$6 \) is not sufficient to cover the cost of the notebooks and the markers. Therefore, the problem as stated does not have a valid solution under the given conditions.

Extra Insights

Tim bought 3 notebooks for \( \$3 \) each, which totals \( 3 \times 3 = \$9 \). However, he only spent \( \$6 \) in total, which suggests there's some arithmetic confusion here since he can't spend less than the cost of the notebooks. To find out how much he spent on the pack of markers, we would typically set up the equation: Total spent = Cost of notebooks + Cost of markers. If \( x \) is the cost of the markers, we can write \( 6 = 9 + x \), leading to \( x = 6 - 9 \), meaning he overdrew his balance by \( \$3 \)! It looks like Tim might need to shop a little more carefully next time!
