FinnZ [79.3K]

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.
