terry earns $6.50 per hour babysitting.
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
my best answer is D is that correct
6.50 per hour means the hourly charge will be 6.50h
so, now what do you think?
does anybody have all the answers for the test i just finished it but i wanna see which ones i got wrong so i know what grade i got
No, your answer is not correct. Let's go through the process step by step.
a. To write a rule that describes how the amount of money Terry earns is a function of the number of hours she spent babysitting, we need to consider that she earns $6.50 per hour. This means that for each hour she babysits, she earns $6.50.
So, the rule can be written as: m(h) = 6.50h, where m(h) represents the amount of money Terry earns (in dollars), and h represents the number of hours she spent babysitting.
b. To find out how much money Terry earns if she babysits for 4 hours and 15 minutes, we first need to convert the 15 minutes to its decimal equivalent. There are 60 minutes in an hour, so we divide 15 by 60:
15 minutes / 60 minutes = 0.25 hours
Now, we can substitute the value of h into our function:
m(4.25) = 6.50 * 4.25
m(4.25) = $27.63
Therefore, the correct option is C. m(h) = 6.50h; $27.63.
