Answer:
Step-by-step explanation:
Let’s estimate the students to 20 and the dollars to 25 so you would multiply 20 by 25 which equals 500 so $500 would be your answer
Answer:
180
Step-by-step explanation:
So, lets go over what we know:
5% of x = 9
Thinking of this in decimal form, this is:
0.05 * x = 9, or 0.05x = 9
To find the answer, we must multiply both sides to get 1x.
Since 0.05 is 1/20 of 1, we must multiply both sides by 20:
0.05x * 20 = 0 * 20:
1x = 180
So the answer is 180!
Hope this helps!
Answer:
a)
We know that:
There is a fixed cost of $7
for each mile, you need to pay $0.65
Then if you take the taxi for "m" miles, the total cost is:
c(m) = $0.65*m + $7
Now we know that Gavin also gives a $3 tip, so we need to add this to the cost:
c(m) = ($0.65*m + $7) + $3 = $0.65*m + $10
c(m) = $0.65*m + $10
Now we know that he paid a total of $62.65
Then:
c(m) = $62.65 = $0.65*m + $10
This is the equation we need to solve in order to find m, the number of miles between Gavin's house and the airport.
b)
$62.65 = $0.65*m + $10
We only need to isolate m, we will get:
$62.65 - $10 = $0.65*m
$52.65/$0.65 = m = 81
This means that there are 81 miles between the airport and Gavin's house.
