They each get one whole one and then half of one.
Let the number of child tickets sold be x, and number of adult tickets be y, then
5.70x + 9.50y = 543.40 . . . (1)
y = 2x . . . (2)
Putting (2) into (1), gives
5.7x + 9.5(2x) = 543.4
5.7x + 19x = 543.4
24.7x = 543.4
x = 543.4/24.7 = 22
Therefore, 22 child tickets were sold.
Answer:
The answer to your question is Ruth needs 3/2 or 1 1/2 more quarts.
Step-by-step explanation:
Data
Oil needed = 5 1/4
Oil in bottle 1 = 2 1/2
Oil in bottle 2 = 1 1/4
Process
1.- Subtract the oil in bottle 1 and bottle 2 to the amount of oil needed.
5 1/4 - 2 1/2 - 1 1/4
-Convert the mixed fractions to improper fractions
5 1/4 = (20 + 1) / 4 = 21/4
2 1/2 = (4 + 1)/2 = 5/2
1 1/4 = (4 + 1)/4 = 5/4
-Substitute
21/4 - 5/2 - 5/4
-Look for the Greatest common factor
4 2 4 2
2 1 2 2
1 1
GCF = 2 x 2 = 4
21/4 - 5/2 - 5/4 = (21 - 10 - 5)/4
= (21 - 15)/4
= 6/4
= 3/2 or 1 1/2
-Conclusion
Ruth needs 3/2 or 1 1/2 more quarts.
