Answer:
1,180 cases
Step-by-step explanation:
The applicable formula in this case is the formula for calculating future value.
A = P x ( 1 + r)^n
where A is the number of cases after 3 years
P is the number of case sold this year
r is percentage increase: 7 %
n is the number of periods : 3 years
Number of cases sold this year = 900 Plus 7% of 900
=107% x 900
=1.07 x 900
=963
A = 963 x ( 1 +7/100)^3
A= 963 x( 1.07 )^3
A =963 x 1.225043
A =1,179.716
A= 1,180 cases
Number of cases = 1,180
