Ian gets $9 for each hour he works and $10for each day he works. To find out how much he makes in a day, he made the equation y=9x+10x, where x is the number of hours he works. Explain why Ian's equation will not tell him how much he makes in a day.
it will not tell him because it only gives him the answer of how many hours he works
i need help :(
I'm only a STUDENT so I DON'T know if this is correct.
The equation says he will multiply 10 times x, but this is unnecessary since he ONLY earns $10 PER DAY. He does not need to multiply the number of hours he works by how much he makes PER DAY. He only needs to multiply 9x. Hope that makes sense lol
Look at where the variables are placed and what they mean. Then look back at the question and look at the words. Try to see if you can find the error from there.
Ian's equation, y = 9x + 10x, is not an accurate representation of how much he makes in a day. The equation implies that the amount Ian earns in a day is determined solely by the number of hours he works. However, this overlooks the fact that Ian also earns a fixed amount of $10 per day.
To accurately calculate how much Ian makes in a day, we need to consider both his hourly rate and the daily fixed amount. One way to modify the equation is to add a constant term representing the fixed daily earnings. Let's call this constant term "c." The revised equation would then be y = 9x + c, where x is the number of hours Ian works and c is the fixed daily earnings.
Therefore, to find out how much Ian makes in a day, we need to know the value of "c" or the fixed daily earning amount. Without that information, the equation cannot accurately determine Ian's daily earnings.
