Answer:
20 chairs
Step-by-step explanation:
Since we are given the amount total budget and the total amount for the desks then the only variable missing is the maximum amount of chairs. This can be solved with the following equation in which s represents the number of chairs, and we simply solve for s.
800 = 320 + 24s ... subtract both sides by 300
500 = 24s ... divide both sides by 24
20.83 = s
Now we see that the maximum number of chairs that the librarian can buy is 20 because 21 would make her go over the budget and you cannot have 0.83 of a chair.

Answer:
4 : 1
Step-by-step explanation:
(3 days : 18 hours) this is a ratio , where both the units must be same before simplifying.
1 day = 24 hours, 3 days = (3 × 24) hours
3 days = 72 hours
Now both the units are same, so we can easily simplify now.
72 hours : 18 hours
36 : 9 = 12 : 3
= 4 : 1 ( Answer)
Answer: 6 hours or 360 minutes
Step-by-step explanation:
First find out how long it takes to deliver to one house.
Convert hours to minutes.
2.5 x 60 = 150 minutes total
Divide to find the time per house
150 minutes / 130 houses = 1.15 minutes per house
Now multiply this rate by the number of houses (312).
312 x 1.15 = 360 minutes
If you want it in hours then divide by 60.
360/60 = 6 hours.
