Set up a proportion.
Let x = the number of students in 29970 who speak 3 or more languages.
285/19 = 29970/x Cross multiply
285 x = 19 * 29970
285x = 569430
x = 569430/285
x = 5415 students speak 3 languages.

Answer:
Required Expression : 7·(s + d) - 25
Step-by-step explanation :
Cost of each plant both buys = $7
No. of plants Stephanie wants to buy = s
Total cost of plants bought by Stephanie = 7·s
No. of plants Diego wants to buy = d
Total cost of plants bought by Diego = 7·d
Total cost = 7·s + 7·d
= 7·(s + d)
Discount applied through coupon = $25
So, Total cost of all their plants with discount = 7·(s + d) - 25
