A DVD club charges nonmembers $20. 50 to purchase a DVD. With a $25 one-time membership fee, members pay $18 per DVD. For what number of DVDs is the cost the same for members and nonmembers on the first purchase? Write an equation that models the situation. Let d represent the number of DVDs. Solve the equation. For what number of DVDs is the cost the same for members and nonmembers’ first purchase from the DVD club?
Answers
A DVD club charges nonmembers $20. 50 to purchase a DVD. Members pay $18 per DVD for a one-time membership cost of $25. The cost is the same for members and nonmembers on the first purchase is 10.
Let's call the number of DVDs "d". For non-members, the cost of purchasing d DVDs is:
Cost for non-members = 20.50d
For members, the cost of purchasing d DVDs is:
Cost for members = 25 + 18d
We want to find the value of d for which the cost is the same for members and non-members. In other words, we want to find the value of d that satisfies the equation:
20.50d = 25 + 18d
To solve for d, we can start by subtracting 18d from both sides of the equation:
2.50d = 25
Then, we can divide both sides by 2.50:
d = 10
Therefore, the cost will be the same for members and non-members on the first purchase if the number of DVDs purchased is 10.

Answer: 11,600 Mexican pesos
Step-by-step explanation:
To determine how many pesos you can buy with $580, you need to know the current exchange rate between the US dollar (USD) and the Mexican peso (MXN). Exchange rates fluctuate, so it's important to check the most up-to-date rate.
Let's assume that the current exchange rate is 1 USD = 20 MXN.
To calculate how many pesos you can buy, you would multiply the amount of dollars you have by the exchange rate:
$580 * 20 MXN/USD = 11,600 MXN
Therefore, with $580, you can buy 11,600 Mexican pesos (MXN). Please note that exchange rates may vary, so it's always a good idea to check the current rate before making any conversions.

Answer:
The two equations are
1) 25 + 49 = 74
2) 74 - 25 = 49
Step-by-step explanation:
Given numbers 74 , 25 and 49
We have to write the equations using the numbers 74, 25 and 49
Since, we can apply two operations addition and subtraction that involves all the three numbers together.
So first equation becomes,
When we add 25 and 49 we get 74
Written mathematically as 25 + 49 = 74
and second equation becomes,
When we subtract 25 from 74 we get 49
Written mathematically as 74 - 25 = 49
Thus, the two equations are
1) 25 + 49 = 74
2) 74 - 25 = 49
7425 ? 49
and = + in math
74250 + 49
