I would use algebra to solve this:
let the amount of child ticket sold be x and the amount of adults ticket sold be 2x
so 2x•9.60+ x•6.30 = 969.00
19.2x+6.30x = 969.00
25.5 x =969.00
x=38
hence ans is 38
an alternative solution would be:
9.60×2 + 6.30 = 25.5
969.00÷25.5= 38
the methods are actually almost the same.
Answer:
13+2h
Step-by-step explanation:
The word "sum" can be related to "addition" and "13 and a number" is just "13" and an exponent.
Answer:
120 = 2³ × 3 × 5
210 = 2 × 3 × 5 × 7
LCM(120 ; 210) = 2³ × 3 × 5 × 7 = 840
Answer:
There are 1,039,584 ways in which this can be done.
Step-by-step explanation:
Total number of black marbles = 17
Total number of blue marbles = 9
The number black marbles to be chosen = 6
The number blue marbles to be chosen = 3
So, we have to choose 6 black from 17 black marbles.
and to choose 3 blue from 9 blue marbles.
So, the number if possible ways to do it :
Now, solving , we get:
solving , we get:
Hence, there are 1,039,584 ways in which this can be done.
