Answer 1

Answer:50 customers would be expected to buy birthday cards next month.

Step-by-step explanation:

Last month customers at a gift shop bought 40 birthday cards, 19 congratulation cards, 20 holiday cards, 21 thank you cards. The total number of greeting cards that the customers bought last month would be

40 + 19 + 20 + 21 = 100

Percentage of customers that bought birthday cards last month would be

40/100 × 100 = 40%

supposed 125 customers by greeting cards next month, the expected number of customers that would buy birthday cards next month would be

40/100 × 125 = 50
