To calculate the total cost of the items purchased, we can break it down step by step.
-
Postcards:
Cost for 2 postcards = 2 * $0.99 = $1.98 -
Keychains:
Cost for 3 keychains = 3 * $1.25 = $3.75 -
Photo frames:
Cost for 4 photo frames = 4 * $5.65 = $22.60
Now, add all these costs together to find the total cost:
\[ \text{Total Cost} = \text{Cost of Postcards} + \text{Cost of Keychains} + \text{Cost of Photo Frames} \] \[ \text{Total Cost} = 1.98 + 3.75 + 22.60 = 28.33 \]
Now, split the total cost among 4 friends:
\[ \text{Cost per person} = \frac{\text{Total Cost}}{4} = \frac{28.33}{4} = 7.08 \]
Thus, each person will owe $7.08.
