Can someone explain how I solve both of these? I’m sort of lost

Answer 1

Answer: 4: C

5:B

Step-by-step explanation:

Answer 2

Answer:

#1) Well buying something 15 percent cheaper is like saying your buying something for 85% of its normal price.

Well a tax is adding onto somethign right? A percent means out of a hundred. A 5 percent tax is addding 5 percent to the hundred so really your paying 105 percent of the price. Convert into decimal you get 1.05

So assuming y is the original and the state Tax being 5% then

(y*0.85)1.05 (last option)

#2) Well we now x is adult tickets and y is child.

Adult tickets are $74

Youth is $35

Now we want to know c or total.

So 74x+35y=c (last option)
