1985year ->275cell phones->100%
1994year -> x cell phones ->100%+360%
40% • (1994-1985)= 40% • 9= 360%
275 cell phone 100%
X cell phones. 100+360%=460%
x=275•460%/100%
x=12420/100
x=1265
99% sure this is a correct answer
x=275 • 460%/100%
x=12,420/100
x=1265
1994-1985= 9 yrs • 40%= 360%

where
PV = the present value (PV) of the money invested
r = the annual interest rate expressed as a decimal fraction
t = the time in years

Net money earned = $ 1537
Step-by-step explanation:
Wage for assembling motorcycle = $125
Number of motor cycles assembled last week = 11
Total money earned = $125 x 11 = $1375
Total payment for test ride $18
Number of motor cycles given for test ride last week = 9
Total money earned in test rides = $18 x 9 = $162
Hence, net money earned last week by Roger= $1375+$162 = $1537
