Answer: $22
Step-by-step explanation:
First we calculate for the sale price.
We have to find how much is 60% of 50.
We do this by:
This equals 30.
We now subtract the 30 from the 50 to get our sale price.
The sale price is $20.
Now we have to add a 10% sales tax. This is done by multiply the percentage and adding 1 to it like this.
This equals 1.1
This is what we will multiply the $20 by.
The total cost is $22.
Answer:
Greg lives 280 miles from the mountains.
Step-by-step explanation:
Given:
Time required to drive to the mountains = 8 hours.
Time required to drive home = 5 hours.
We need to find the distance Greg live from the mountains.
Solution:
Let the average rate while driving to the mountains be 'x'.
So rate while returning home =
Now we know that;
Distance is equal to Speed times Time.
So we can say that;
Distance while travelling the mountain =
Distance while returning home =
Now we know that;
Distance while travelling the mountain and Distance while returning home will both be equal.
so we get;
Combining like terms we get;
Dividing both side by 3 we get;
Substituting the value of x in any of the Distance equation we get;
Distance =
Hence Greg lives 280 miles from the mountains.
