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.

213 students can take Spanish
283 students can take Spanish
425 students can take Spanish
638 students can take Spanish

If there are 3 times as many Spanish classes as French classes, then there must be 1 French class and 3 Spanish classes.

To find the number of students in each Spanish class, divide the total number of students (850) by the total number of classes (4):
850 / 4 = 212.5
Since we need to round to the nearest whole number, there are 213 students in each Spanish class.
Since there are 3 Spanish classes, the total number of students who can choose Spanish is:
213 * 3 = 639
Rounded to the nearest whole number, 639 students can choose Spanish.
