The length of DE is 39 and the length of EF is 36 because we can see from side AC and DF that triangle DEF is just triangle ABC dilated by 3.
So first we need to find what percent of the students walk to school.
50 + 35 = 85% don't walk leaving only 15% that walk to school,
To find the 15% percent that DO walk we multiply .15 by the total number of people.
.15 x 1640 = 246 people walk to school
The first choice should be used.
2 3 4 cannot be it because they don’t use the correct numbers.
Here is the set up:
Let T = total deposit
T = (231.09) + 987.67+ 9.00 + 45.00 + 80.00 + 3.50 + 2.50 + 0.90 + 0.64
Take it from here.
