Answer:
7.5
Step-by-step explanation:
let x be the ticket and y the popcorn
x+y=15
x+3y=30
solve for x and y using simultaneous equations
x=7.5
y=7.5
Functions:graph B,mapping A, Table B
Grape B is a function because it passes the vertical line test ( meaning when I draw a vertical line any where on the graph the line only touched one point),mapping A is a function because each x value has only one y value same with table.
Non function: graph A, mapping B, Table A
Graph A does not pass vertical line test so it is not a function, mapping B and Table A both have an x value that has two y values and that is not a function.
Answer:

Step-by-step explanation:
Fiona drives 3 1/2 hours on highway = 3.5 hours
average 60 miles per hour on highway.
Then 3.5 * 60 =210 miles
1 1/2 hours in the city = 1.5 hours
average 30 miles per hour in city
Then 1.5 *30 = 45 miles
So
Fiona drives 210 miles on highway and 45 miles in city.
Total of her trip to her grandmother's house equals:
210 + 45 = 255 miles
She drives 3.5 on highway and 1.5 in the city, then total driving should be:
3.5 + 1.5 = 5 hours
Average speed for the entire trip:
255 /5 = 51 miles
