Question

4. What percent of 550 metres is 225 metres?
5. In a plane, 90% of the seats are filled. 30 seats are empty. Find the number of seats on the plane​

Answer 1

Answer:

Step-by-step explanation:

225/550 *100 = 40.90

y - (90/100 * y) = 30

y - 9/10 = 30

(10y - 9y) / 10 = 30

y/10 = 30

y = 300

So, 300 seats (mark as brainlist ;_;)
