Answer:
x = price of balcony tickets = $7
y = price of orchestra tickets = $21
Step-by-step explanation:
Let
x = price of balcony tickets
y = price of orchestra tickets
y = 3x (1)
148y + 76x = 3,640 (2)
Substitute y = 3x into (2)
148y + 76x = 3,640 (2)
148(3x) + 76x = 3,640
444x + 76x = 3,640
520x = 3,640
x = 3,640/520
x = 7
Substitute x = 7 into (1)
y = 3x (1)
y = 3(7)
y = 21
x = price of balcony tickets = $7
y = price of orchestra tickets = $21
Use the distributive property of multiplication to simplify.
-6x + 9y + 15.
Answer: The car has to sell for $20000
Step-by-step explanation:
Let x represent the price that the car would have to sell for in order for these two job opportunities to pay Jim the same amount.
Ace Cars says they will pay Jim a 10% commission on the sale price of each car. It means that his pay would be
10/100 × x = 0.1x
Budget Cars says they will pay him $500 per week plus a 7.5% commission on the sale price of each car. It means that his pay would be
500 + 0.075x
For boths pays to be the same, it means that
0.1x = 500 + 0.075x
0.1x - 0.075x = 500
0.025x = 500
x = 500/0.025
x = 20000
The car has to sell for $20000
Answer:
D) 5/12
Step-by-step explanation:
Suppose there are 30 girls at the school. Then the proportions tell you that 12 of them study music, and 5 of them study both music and dance.
Then 5 of the 12 girls who study music also study dance. That fraction is 5/12.
_____
We chose 30 because it is the least common multiple of the denominators of the fractions (2/5, 3/5, 1/6) in the problem statement.
Of course, you know that 2/5·30 = 12, and 1/6·30 = 5.
