Answer:
Expression: p = 320 x 1.2
Your price: $384
Step-by-step explanation:
Finding 20% is the same as multiplying that number by 0.2 adding it on to the original number. This can also be represented as multiplying by 1.2.
This means the expression is p = 320 x 1.2, where p is the new price.
This gives you $384.
