To calculate how much money Sue can expect to spend, we first need to calculate the cost of the gift cards for her 6 friends and family members.
The cost of the gift cards is: \[ 6 \text{ people} \times 20 \text{ dollars/person} = 120 \text{ dollars} \]
Next, we add the cost of the toys for her dog: \[ 120 \text{ dollars} + 17 \text{ dollars} = 137 \text{ dollars} \]
Therefore, the total amount Sue can expect to spend is: \[ \text{$137} \]
