To find out how much money Michael spent in total, we need to calculate the cost of each item and then sum them up.
-
Cost of notebooks: \[ 3 \text{ notebooks} \times 2.75 \text{ dollars/notebook} = 8.25 \text{ dollars} \]
-
Cost of packs of pens: \[ 2 \text{ packs of pens} \times 1.80 \text{ dollars/pack} = 3.60 \text{ dollars} \]
-
Cost of the bag of chips: \[ 3.35 \text{ dollars} \]
Now, we can add all these amounts together: \[ 8.25 \text{ dollars} + 3.60 \text{ dollars} + 3.35 \text{ dollars} \]
Calculating the total: \[ 8.25 + 3.60 = 11.85 \] \[ 11.85 + 3.35 = 15.20 \]
Thus, Michael spent a total of $15.20.
