X + y = 120000
0.15x - 0.10y = 5500
Multiply both sides of bottom by 100 to remove decimals
x + y = 120000
15x - 10y = 550000
Multiply both sides of top by 10
10x + 10y = 1200000
15x - 10y = 550000
Add the two
25x = 1750000
x = 70000

Answer: 8/9 cups
Step-by-step explanation:
The word 'of' means 'times' as far as fractions are concerned. In this case, we have 1/3 of 2 1/3.
First, it is a good idea to make 2 1/3 an improper fraction - as 8/3, so now we have:
1/3 of 8/3, but since 'of' means 'times' we have,
1/3 x 8/3 = 8/9
The answer is 8/9 cups.
120-(120*20%) = 120-24 = 96
Natasha paid $96.
0.8p represents how much the price was when Natasha paid.
90 days.
For this question you just need to find the least common multiple of 18 and 30. That can be found by first finding the prime factorization of each number. 18 = 2 * 3 * 3 and 30 = 2 * 3 * 5. Then you multiply the 2 * 3 * 3 * 5, you ignore the 3 from 30 because 18 has more 3s. The answer is 90.
