Answer:
1/ 0.6 = x / 250..1 dollar to 0.6 euros = x dollars to 250 euros
cross multiply
(0.6)(x) = (250)(1)
0.6x = 250
x = 250/0.6
x = 416.67 american dollars
$416.67
Step-by-step explanation:
The conversion rate is 1 dollar to every 0.6 euros.
This gives us the ratio 1/0.6.
Setting up the ratio for the cost of the ring, we have x/250. This gives us the proportion:
1/0.6 = x/250
Cross multiplying,
1(250) = 0.6(x)
250 = 0.6x
Divide both sides by 0.6:
250/0.6 = 0.6x/0.6
416.67 = x
yes
21-7=14 so x=14. 7x2=14 so that means that there are twice as many flute players
