Answer:
$160/5
Step-by-step explanation:
160/5 would be 32 and 315/9 would be 35. 32 is less than 35 so $160/5 would be the better deal.
Y = 18( 0.58) ^t
It would be written as :
Y = 18(0.11) ^ (t/4)
Y = 18 (0.11 ^ (1/4)) ^ t
But
0.11 ^ (1/4) = 0.5759
Plug the value
Y = 18 (0.5759) ^ t
Two decimal point :
Y = 18 (0.58) ^ t
