1000 views=£2<br> how many views are required to make £31?
dedylja [7]
1000 = £2
10 x 1000 = 10,000 = £20
15,000 = £30
16,000 = £32
Not sure if you want specifically 31 but I’d say if you do it would be 15,000 views

1. A shop makes tables and chairs. Each table takes 9
solniwko [45]

Answer:

9t + 4c ≤ 250

3t + 2c ≤ 80

Step-by-step explanation:

t is the number of tables

c is the number of chairs

Each table takes 9 hours to assemble and 3 hours to finish, so t tables take 9t hours to assemble and 3t hours to finish.

Each chair takes 4 hours to assemble and 2 hours to finish, so c chairs take 4c hours to assemble and 2c hours to finish.

Therefore, total assembly time is 9t + 4c.  Total finishing time is 3t + 2c.

Total assembly time is at most 250, and total finishing time is at most 80.

9t + 4c ≤ 250

3t + 2c ≤ 80
