Selma's class is making care packages to give to victims of a natural disaster. Selma packs one box in 5 minutes and has already packed 12 boxes. Her friend Trudy packs one box in 7 minutes and has already packed 18 boxes. How many more minutes does each need to work in order to have backed the same number of boxes?

Answers

Every 35 minutes Selma packs 7 boxes, while Trudy packs 5 boxes.

Thus every 35 minutes Selma decreases the difference between them in 2 boxes.

Since the original difference was 6 boxes, Selma needs 3 times 35 minutes, or 105 minutes, in all, to catch Trudy.

Answer- 105 minutes, or 1 hour and 45 minutes.

A theatre sells 1986 tickets. 234 more adult tickets are sold than child tickets, and 186 more child tickets are sold than student tickets. How many child tickets are sold?

Answers

Answer:

646 child tickets are sold

Step-by-step explanation:

Let c represent the number of child tickets sold. Then (c-186) is the number of student tickets sold, and (c+234) is the number of adult tickets sold. The total number sold is ...

(c -186) + c + (c+234) = 1986

3c +48 = 1986 . . . simplify

c + 16 = 662 . . . . divide by 3

c = 646 . . . . . . . . . subtract 16

The number of child tickets sold is 646.

Arthur baked 1 7/12 dozen muffins. Nina baked 1 1/12 dozen muffins. How many dozen muffins did they bake?

Answers

Answer:

Total number of dozen muffins they both bake is $2(8)/(12)$

Step-by-step explanation:

Given : Arthur baked $1(7)/(12)$ dozen muffins. Nina baked $1(1)/(12)$ dozen muffins.

We have to find the total number of dozen muffins did they both bake.

To find the total number of dozen muffins did they both bake is equal to number of dozen of muffins Arthur bake and number of dozen of muffins Nina bake

That is

Mathematically written as ,

Total number of dozen muffins = number of dozen of muffins Arthur bake + number of dozen of muffins Nina bake

Given : Arthur baked $1(7)/(12)$ dozen muffins

and Nina baked $1(1)/(12)$ dozen muffins.

Total number of dozen muffins = $1(7)/(12)+1(1)/(12)$
