Answer:
a) Trained 730 hours
b) 30.42 days
c) 4.35 weeks
Step-by-step explanation:
Hours the dog trained:
2 * 365 = 730
In days:
730/24 ≈ 30.42
In weeks:
30.42/7 ≈ 4.35
Answer:
See below.
Step-by-step explanation:
So, Nikki earns $12 per hour.
And she also earns a 5% or 0.05 commission of her total sales each day.
On Saturday, she worked eight hours and she earned $139. In other words, she earned 8(12) or $96 from working her hours and another $43 (139-96) from her commission.
Thus:
Where x represents Nikki's total sales on Saturday.
Further notes:
To solve, subtract 96 from both sides and divide by 0.05:
Thus, her total sales that day were $860.
Answer:
4 additional days.
Step-by-step explanation:
So the total charge is $575.
It costs $355 for 1 week of use of the van.
1 week is 7 days.
It costs $55 for each extra day of use of the van.
575=55d+355
d is for the unknown extra amount of days.
subtract 355 from both sides
220=55d
divide by 55 on both sides
4=d
So, the Dakotas used the van for 4 additional days. So in total the used the van for 4+7 days.
4+7=11 total days.
But the answer to the question is 4 days, because it specifically ask for additional days.
Call the number x. Then we write
2x - 5 = 17
To solve, add 5 and divide by 2...
2x = 22
x = 11
To solve equations, all we must do is isolate the variable and simplify. In this case, we need to get rid of the "/7" because it i with our "e." To do this, we should do the reverse operation of "/7" on both sides, and them simplify.
-5=e/7
*7 *7
-35=e
Using the math above, we can see that e=-35.
