The area is 210 square millimeters
let cat food = x
total plus 5% = 105% = 1.05
1.05 * (11.50 + X) = 16.80
12.075 + 1.05x = 16.80
1.05x = 16.80-12.075
1.05x = 4.725
x = 4.725 / 1.05
x= 4.50
the cat food cost $4.50
11.50 +4.50 = 16.00
16.00 * 0.05 = 0.80
16.00 + 0.80 = 16.80

Answer:
1st one I hope this helped!
Step-by-step explanation:
So if she estimated 45 and has 41, then the error is 45-41=4
so find what percent=4/45
divide
4/45=0.0888888
percent=parts out of 100 so
x/100=x%
so 0.0888/1 times 100/100=8.8888/100
the answer is 8.88888% or rounded up is 8.9%
the answer is C
