Answer:
15%
Step-by-step explanation:
The cost of 2 adults and 2 children without the discount is
2 adults = 2 (55) = 110
2 children = 2 (45) = 90
Total cost = 110+90 = 200
The original price is 200 and the new price is 170
Percentage discount = (Original price - new price)/ original price * 100%
= (200-170)/200 * 100%
= 30/200 * 100%
= .15 * 100%
= 15%
PEMDAS
(9)(5) + 8
45 + 8
53
If 4y-2=26 then 4y=26+2
4y=28 divide both side by 4
y=28/4=7 opt A
