A phone company uses the equation y=0.15x+10 to find y, the monthly charges for a customer sending x text messages. How many text messages are sent if the monthly charge is $77.50?
21?
it's 21 (i think idk)
The answer is 21 because 77.50x0.15=11.625 then you add the ten which equals 21.
Can i please know the right answer
506 idk
To find the number of text messages sent if the monthly charge is $77.50, we can use the given equation: y = 0.15x + 10.
We already know that the monthly charge (y) is $77.50. So, we can substitute this value into the equation to solve for x.
77.50 = 0.15x + 10
To isolate x, we need to get rid of the constant term on the right side of the equation. We can do this by subtracting 10 from both sides:
77.50 - 10 = 0.15x
67.50 = 0.15x
Next, we need to isolate x, so we can divide both sides of the equation by 0.15:
67.50 / 0.15 = x
This gives us:
450 = x
Therefore, if the monthly charge is $77.50, the customer has sent 450 text messages.
No.
76.50 divided by 0.15 = ?
y=0.15x+10
77.50 = 0.15x + 10
76.50 = 0.15x
? = x
