Answer:
A
Step-by-step explanation:
An hour is 60 minutes.
The trip to the arena + The return drive = 60 mintues.
Since the return drive is 8 minutes shorter, if you added 8 minutes it would be the same length as the trip to the arena.
The return drive + 8 minutes = The trip to the arena
Let's represent these two equations with variables.
x + r = 60
r + 8 = x
What we do now is use substitution. Since r + 8 = x, we can replace x from the first equation with r + 8.
x + r = 60
r + 8 + r = 60
2r + 8 = 60
2r = 52
r = 26
Then use r in an earlier equation to find a.
r + 8 = x
26 + 8 = x
x = 34
Answer:
y = 5 + 2.5x
Step-by-step explanation:
1: they start off with a $5 entry fee, so even if no pounds of apples were bought, they would still have to pay $5.
2: For each pound of apples bought, it costs 2.5, therefore if they bought 3 pounds, it would be 3 x 2.5, if they bought 7 pounds, it would be 7 x 2.5. If they bought x pounds, it would be x x 2.5 = 2.5x
3: Putting that together, the total cost is the entry fee plus the money spent on apples.
4: Y (total cost) = 5 + 2.5x

1 chicken meal = $5
9 chicken meals = 9($5)= $45
-
1 burger meal = $6
15 burger meals = 15($6) = $90
-
Total amount = $90+$45 = $135
-
Percent spent on chicken meals = [$40 ÷ $135] x 100
= 0.296 x 100
= 29.6% or approximately 30%
