Jim is 16 because take away 21-5=16.Now Cindy 21-4=17.Cindy is 17.Jim is 16.
She has $55. She spent $22.50 on rides so now she has $32.50 . Then she spends $14.25 on lunch and snack so now she has $18.25.
A. would be wrong because Courtney IS correct, she has $18.25 left.
C. is also wrong because, again, Courtney IS correct.
So the only option left is B and it explains why Courtney is correct.
Option B is the correct answer.
Hope this helps.
Ignore the scribbles
Search up Elimination and substitution
I can’t see it it’s to blurry for me
Subtract the exponents when the base number is the same.
2 - 7 = -5
So 9^-5 or 1/9^5.
