Correct Question
Mara thinks x ≤ 6 will earn the highest score here.
David thinks x < 6 will.
Who is correct?
Answer:
Mara is correct
Step-by-step explanation:
In the above question, we are given two inequality equations
1) Mara: x ≤ 6
2) David : x < 6
For David , x < 6 means the score which is represented by x is less than 6
For Mara, x ≤ 6 means the score which is represented by x is less than or equal to 6
Therefore, Mara is correct because x ≤ 6 will earn the highest score here.
1 .Fridays and Saturdays, she works 16 hours
16 x $9.70 = $155.20

3.hourly rate of $11.28 per hour worked 46 hours last week. She works overtime for hours exceeding 40 hours in a week. She is paid overtime at a rate of time and a half. What was her gross pay last week?
$11.28 x 40 = $451.20 ---normal 40 hours paid

11.28 + 11.28/ 2 = $16.92 (overtime pays a rate of time and a half)
6 * $16.92 = $101.52
$451.20(40hours) + $101.52(6hours overtime) = $552.72
answer: her gross pay last week was $552.72

Answer:
John's mother has the present age that is four less than the 8 times the present age of John.
If his mother has the age of 28 years now, then find John's present age.
Step-by-step explanation:
We have to write a word problem that would have the equation 8x - 4 = 28.
John's mother has the present age that is four less than the 8 times the present age of John.
If his mother has the age of 28 years now, then find John's present age.
So, if we consider the age of John as x years, then we will get the equation as 8x - 4 = 28. (Answer)
