a. write a rule to describe how the amount of money m earned is a function of the number of hours h spent babysitting.
b. how much money does terry earn if she babysits for 4 hours and 15 minutes?
A. m(h)= 4h+ 15:$26.15
B. m(h)= h/6.50;$0.65
C. m(h)=6.50h;$27.63
D. m(h)= 6.50h= $26.98
Can you please check. My Answer is D
Thank you :D
So is my answer correct or do I have to recalculate?
check your arithmetic
Why do you think Scott told you to check your arithmetic?
To determine the correct answer, let's approach the problem step by step:
a. To write a rule describing how the amount of money earned (m) is a function of the number of hours spent babysitting (h), we can use the information given that Terry earns $6.50 per hour. This means that for each hour Terry babysits, she earns $6.50. Therefore, the rule can be written as:
m(h) = 6.50h
b. Next, we need to calculate how much money Terry earns if she babysits for 4 hours and 15 minutes. We first need to convert the 15 minutes into a decimal value of hours. Since there are 60 minutes in an hour, 15 minutes is equivalent to 15/60 = 0.25 hour.
Now, we can substitute the value of h into the rule to calculate the amount of money Terry earns:
m(4.25) = 6.50 * 4.25 = $27.63
So the correct answer is C. m(h) = 6.50h, which corresponds to $27.63.
Therefore, your answer of D is incorrect, and the correct answer is C.
