Weekly sales of your Lord of the Rings T-shirts have been falling by 5% per week. Assuming that you are now selling 50 T-shirts per week, how many shirts will you sell during the coming year?

Respuesta :

Answer:

47.45

Step-by-step explanation:

This is an arithmetic progression or regression there fore the formulae to use is a+(n-1) d

a = first term = 50

n = number of week= 52

d= common difference= -0.05 or 5%

50+(52-1)*-0.05= 50 + (51)*-0.05
