Answer:
- 30 adult tickets,
- 50 kids tickets
Step-by-step explanation:
<u>Given</u>
- Cost of adult ticket = $8.50
- Cost of kids ticket = $7.00
- Number of tickets = 80
- Total cost = $605
Let the adult ticket be a and kids be k
<u>We got equations</u>
- a + k = 80
- 8.5a + 7k = 605
<u>From the first equation we get</u>
<u>Substituting k in the second equation</u>
- 8.5a + 7(80 - a) = 605
- 8.5a - 7a + 560= 605
- 1.5a = 45
- a = 45/1.5
- a = 30
<u>Then finding k</u>
Answer:
B. 7.94 × 10^8 miles
Step-by-step explanation:
Given that
Earth is approximately 9.3 × 107 miles from the sun.
Saturn is approximately 8.87 × 108 miles from the sun.
We need to find out how much farther is saturn from the sun than earth is
So,
Earth - Sun = 9.3 × 10^7 miles
Saturn - Sun = 8.87 × 10^8 miles
Now
= 8.87 × 10^8 - 9.3 × 10^7
= 88.7 × 10^7 - 9.3 × 10^7
= 79.4 × 10^7
= 7.94 × 10 ^8
= 794,000,000 miles
Hence, saturn is 7.94 × 10^8 miles farther from Sun than Earth is
