PART A
alligators:
x = total number of alligators
n = number of years
x=20*1.25^n
crocodiles:
y = total number of crocodiles
n = number of years
y=25+10n
PART B
alligators
x=20*1.25^4 = 48.82 round up to 49
crocodiles 25 +10(2) = 25+20 = 45
Part C
7 years
20(1.25^n)=25+10n
1.25^n=1.25+0.5n
n=7
check:
alligators 20+1.25^7 = 95.36
crocodiles = 25+10(7) = 95
Answer:
92
Step-by-step explanation:
If w=8 then you would multiply 9 by 8 which is 72. Then you would multiply 5 with 4 since x equals 4 which is 20. Then you would add 72+20 which gives you your answer which is 92
