The correct answer is 45+45(0.15). This is because you need to first count the price, and then add on the tip which is a certain percentage of that price. Hope this helped!
Answer:
1. 
2. 
Step-by-step explanation:
all you are doing is solving for "y"
Answer: B
Trust me I took the test right now
Answer:
x+y=4+8=12
$12 for one of each
or if you mean indivually (the wording confused me)
$4 for child, $8 for adult
Step-by-step explanation:
x=adult
y=child
2x+10y=56
4x+5y=52
iin order to be able to subtract values and find x and y im going to multiply 4x+5y=52 by two and get 8x+10y=104
8x+10y=104
-2x+10y=56
6x=48 divide each side by 6
x=8
plug 8 back into an equation to find cost of y
2(8)+10y=56
-16 -16
10y=40
y=4
