Replace 7 for the variable, t. N= 2000(2(7))= 28000
2000 smartphones and 1500 flip phones
4-3=1
1x500=500
500x4=2000
500x3=1500
Answer:
512
Step-by-step explanation:
1st term =a
common ratio = r
a*r with the exponent n-1
a=4 r=2 n=8
8th term 4*(2 at the seventh power)= 512
OR
1st term :4
2nd term = 4*2=8
3rd term 8*2=16
4th term 12*2=32...............8th term 256*2=512
5b + r = 30
the cost per item * the number of items sold = the profit
