Answer:
1. $2.50
2. 120 bagels
Step-by-step explanation:
1. First, we are told that for every twelve bagels, it costs $5
we can use this information to set up the ratio:
Now, for the first question, we have to figure out how much it would cost to buy six bagels. We can use x for the cost since it is unknown as write the ratio:
since the rate of change is constant, we can set these two ratios equal to each other and cross multiply to solve for x.
=
5 * 6 = 12 * x
30 = 12x
x = 2.5
it would cost $2.50 for 6 bagels.
2. For this problem, we can use the same first ratio of:
Now in this problem, the amount of bagels is unknown. we can use y to represent the number of bagels and set up the ratio of
we can make these two ratios equal to each other and cross multiply
=
5 * y = 12 * 50
5y = 600
y = 120
For $50, you can buy 120 bagels
hope this helped!
For number 7 the answer should be 20%. 10 is 50% and the other 6 is 30%.

Answer:
It represents the cost of the DVD player.
____________________________________________________
Step-by-step explanation:
The reason why it represents the cost of the DVD player is because in the question, it doesn't mention anything about buying multiple DVD players. Ebony would need to buy many DVD's, but doesn't need many DVD players because ebony could use one for all of the DVD's. If you noticed in the question, it says "a DVD player," what this means is that Ebony is only going to buy one DVD player, since it's singular (without and s at the end).
The equation is saying that she starts off with buying 1 DVD player for 200 dollars; and, she is buying n (number of DVDs) for 20 dollars each.
This shows that the 200 in the equation in the question represents the cost of the DVD player.
