268 / 28 = 9.57
9.57 x 21 = 201
Therefore, the answer is 201.
T_n = 3 * T_(n-1)
Long way (always works!)
T_5 = 3*T_4,
T_4 = 3*T_3
T_3 = 3*T_2
T_2 = 3*T_1
T_5 = 3*3*3*3*T_1 = 81*T_1 = 81*8 = 648!
Short way (sometimes it works!)
T_n = 3^(n-1) * T_1 (this case is a geometric series of ratio-=3)
T_5 = 3^4*8 = 648
According to my calculations,
A. is the correct answer.
8√5
The cost of the tablet computer is less in France. It is $8.
Step-by-step explanation:
Cost in France = 600 euros
75 euros = 1 dollar
600 euros = 600/75 dollars
=$ 8
Cost in Britain = 533 pounds
65 pounds = 1 dollar
533 pounds = 533/65 dollars
= $8.2
The cost of the tablet computer is less in France. It is $8.
