Mikayla found a website that allows her to download songs for $1.30 each and ringtones for $0.75 each. Mikayla downloads x songs and 2 ringtones.
Which equation can be used to find y, the total cost that Mikayla must pay?
Responses
A y = 1.30x + 0.75y = 1.30 x + 0.75
B y = 1.30x + 1.50y = 1.30 x + 1.50
C y = 1.50x + 1.30y = 1.50 x + 1.30
D y = 0.75x + 2.60
The correct answer is A: y = 1.30x + 0.75.
To find the total cost (y), we need to add the cost of the songs (which is $1.30 each and there are x of them) and the cost of the ringtones (which is $0.75 each and there are 2 of them). This gives us the equation:
y = 1.30x + 0.75(2)
Simplifying this equation:
y = 1.30x + 1.50
This matches option A.
D. y = 0.75x + 2.60
Because Mikayla downloads x songs for $1.30 each, the cost of songs would be 1.30x. As she downloads 2 ringtones for $0.75 each, the cost of ringtones would be 2 * 0.75 = 1.50. Thus, the equation to find the total cost would be y = 1.30x + 1.50. However, since we already have the equation for the total cost y, the options provided do not match the correct equation. Therefore, the answer is not among the options provided.
The correct equation to find the total cost that Mikayla must pay is:
A) y = 1.30x + 0.75
To determine the equation that can be used to find the total cost that Mikayla must pay, let's break down the problem.
Mikayla downloads x songs, each costing $1.30, and 2 ringtones, each costing $0.75.
The total cost of the songs can be calculated by multiplying the number of songs (x) by the cost per song ($1.30). So, the cost of the songs is 1.30x.
Similarly, the total cost of the ringtones can be calculated by multiplying the number of ringtones (2) by the cost per ringtone ($0.75). So, the cost of the ringtones is 2 * $0.75 = $1.50.
Now, to find the total cost that Mikayla must pay, we add the cost of the songs and the cost of the ringtones together. So, the equation can be written as y = 1.30x + 1.50.
Therefore, the correct equation is B: y = 1.30x + 1.50.
