Since 25% is 1/4, you multiply 60 by 1/4 to get how many students took Spanish class last year. So, 60 times 1/4 is 60/4, which is 15. Then you subtract 15 from 60 to get 45. So, 45 students took Spanish class last year.
Answer: option B is the correct answer.
Step-by-step explanation:
Susan drove at an average speed of 30 miles per hour for the first 30 miles of a trip.
Time = distance/speed
This means that time spent by Susan in travelling the first 30 miles would be
Time = 30/30 = 1 hour
He travelled at an average speed of 60 miles per hour for the remaining 30 miles of the trip.
Time = 30/60 = 0.5 hours
Total distance travelled is 30 + 30 = 60 miles.
Total time spent = 1 + 0.5 = 1.5 hours
Speed = distance/time
Average speed = 60/1.5 = 40 miles per hour.
I think the answer is three
(1) The expected number of copies sold is 75
(2) The expected wage is $720
Explanation:
From the graph, we can see that x represents the number of copiers sold.
y represents the wages.
The equation of the graph is 
(1) Given that an employee earn $570.
We need to determine the number of copiers sold.
Let us substitute
in the equation
, we get,



Thus, the number of copiers sold is 75
(2) Given that if an employee sells 100 copiers, we need to determine the expected wage.
Let us substitute
in the equation
, we get,



Thus, the expected wage is $720
