Problem
(1) Jorge takes his friends out for smoothies. He buys 5 smoothies and leaves a \( \$ 3 \) tip, paying a total of \( \$ 23 \). He wants to know the price of one smoothie. Another way to find the price of one smoothie is by writing and solving an equation. (1) Which equation describes the situation? price of 1 smoothie + tip \( =\$ 23 \) \( (5 \) smoothies) (price of 1 smoothie) + tip \( =\$ 23 \) price of 1 smoothie - tip \( =\$ 23 \) \( (5 \) smoothies) (price of 1 smoothie \( )- \) tip \( =\$ 23 \)
Solution
Step 1 ：\(5\cdot(\text{price of 1 smoothie})+\text{tip}=\$23\)
Step 2 ：\(5\cdot(\text{price of 1 smoothie})+\$3=\$23\)
Step 3 ：\(\text{price of 1 smoothie} = \frac{\$20}{5}\)
