The incoming 7th grade class has choice of FRENCH or SPANISH as a language elective. There are 3 times as many Spanish classes as French classes (or 3 to 1). How many students can choose Spanish if there are 850 student? Round to the nearest whole number.
(1 point)
A. 213 students can take Spanish
B. 283 students can take Spanish
C. 425 students can take Spanish
D. 638 students can take Spanish
Let the number of French classes be x.
Then the number of Spanish classes is 3x.
The total number of classes is x + 3x = 4x.
Since there are 850 students in total, 4x = 850.
Dividing both sides by 4, we get x = 212.5.
Since the number of classes must be a whole number, we can round down to x = 212.
Therefore, the number of Spanish classes is 3x = 3(212) = 636.
Therefore, the number of students that can choose Spanish is 636.
Rounding to the nearest whole number, the answer is 638.
Therefore, the correct answer is D. 638 students can take Spanish.
