(For the adding ones ) I also simplified them.
Answer:
Washer = $616, Dryer = $308
Step-by-step explanation:
When something is twice the cost of something else but add up to be a total number that means 2/3rds is one item and 1/3 is the other.
924 / 3 = 308
308 * 2 = 616
308 + 616 = 924
I know you posted this in 2017, but here's the answer anyways.
It is 1/2 because every time you multiply the number before, you multiply it by 1/2 to get the next number.
Let the number of child tickets sold be x, and number of adult tickets be y, then
5.70x + 9.50y = 543.40 . . . (1)
y = 2x . . . (2)
Putting (2) into (1), gives
5.7x + 9.5(2x) = 543.4
5.7x + 19x = 543.4
24.7x = 543.4
x = 543.4/24.7 = 22
Therefore, 22 child tickets were sold.
