Answer:
360/9=40
Step-by-step explanation:
8* oranges + 1 graperfuit = 4.60
6* oranges + 3 grapefruit = 4.80
multiply the first equation by 3
24 oranges + 3 grapefruit = 13.8
subtract the 2nd equation
24 oranges + 3 grapefruit = 13.8
-6* oranges + 3 grapefruit = 4.80
---------------------------------------------------
18 oranges = 9
oranges = .50
6 oranges + 3 grapefruit = 4.80
6 * .5 + 3 grapefruit = 4.80
3 + 3 grapefruit = 4.80
subtract 3 from each side
3 grapefruit = 1.80
grapefruit = .60
Answer: oranges $ .50
grapefruit = $.60
To solve this we would need to make two equations. One equation accounts for the number of hot dogs and sandwiches and the other is the total cost
X + Y = 985
2.95x + 9.95y = 7343.75
Solve for one variable and plug it into the other equation. And solve for the next variable.
X = hotdogs
Y = sandwiches.
The answer would be A 1 7/18
Let x be the number of adult tickets sold.
x + 2x = 357
3x = 357
x = 357/3
x = 119
There were 119 adults tickets sold.
