c)Number of counties Florida has: 67
Number of counties Georgia has: 159
Step-by-step explanationStep 1
set the equations
let a represents the number of counties in Arizona
let f represents the number of counties florida
so
a)Florida has 8 less than 5 times the number of counes a,in arizona
b) Georgia has 25 more than twice the number of counties f in florida, in other words, you have to add 25 to twice (f) to obtain the number of counties ofr Georgia
Step 2
c)
Arizona has 15 counties
so
a=15
replace in equation (1) to find f
hence,
Number of counties Florida has: 67
now, replace in equation (2) to find G
hence,
Number of counties Georgia has: 159
