Answer:
The last choice: log 25 Over log 8
Step-by-step explanation:
Because the change of base formula says:
log (subscript 8) of 25 = log (25) / log (8)
let log be the Common Log without subscripts
8ths are divided by 12.5 so 3 * 12.5 is 37.5
10ths are divided by 10 so 4 * 10 is 40
3/8 is < / = 4/10
(a) total profit
=11000*24%+14000*15%
=2640+2100
=$4740
(b) percent profit
=4740/(11000+14000)
= 0.1895
=18.96%
