0. a store is hoping an advertising campaign will increase their number of customers by 30%. they currently have about 80 customers a day. a. how many customers will they have if their campaign is successful? b. if they increase to 120 customers a day, were they successful?

The store wants to increase customers by 30%. They currently have 80 customers per day.

First thing to do is find 30% of the customers they have:

= 30% x 80

= 24 people

If they increase by 30%, they will go to:

= 80 + 24

= 104 people per day

If they increase to 120 customers. their percentage increase would be:

= (New number of customers - Old number) / Old number

= (120 - 80) / 80

= 50%

In conclusion, 50% is more than 30% so they will have been successful.
