Answer:
The cost of one hot dog is $1.5 and the cost of one drink is $2.
Step-by-step explanation:
Let
<em>h</em> = the cost of a hog dog and <em>d</em><em> </em>= the cost of a drink
We know from the information given that:
- Carl bought 5 hot dogs and 3 drinks and paid $13.50. This is equal to
- Susan purchased 2 hot dogs and 3 drinks and was charged $9.00. This is equal to
So we have a system of equations
We can solve by elimination as follows:
Subtract from
Therefore
<em>h</em> = $1.5 and <em>d</em><em> </em>= $2

Answer:
12.5
Step-by-step explanation:
There are 12 peppers in each bottle of hot sauce
8 seconds
The hardest part of this is setting up the equation -- the calculations are pretty easy.
You're told that the time (needed to go from 0 to 100 MPH) is inversely proportional to the horsepower: what this means is that as horsepower gets larger, time gets smaller. This makes sense since the more horsepower you have, the less time it will take you to get to 100 MPH
You can think of this as:
200 HP = 10 seconds
250 HP = x seconds
You set the equation up as:
250 HP / 200 HP = 10 sec / x sec
Now, just cross multiply and solve:
250 / 200 = 10 / x
250x = (200 x 10)
250x = 2000
x = 2000 / 250
x = 8
So, as you increase the horsepower from 200 to 250, the time decreases from 10 seconds to 8 seconds.
Hope this helps!
Good luck.
