Answer:$51.2
Step-by-step explanation:
We have been given that at the restaurant, the cost of the meal before tax was $40. The tax is 8.5%.
The cost after tax would be .
Sheri wants to leave at least an 18% tip. The cost of meal after tip would be .
Therefore, the total cost of the dinner would be $51.2.
Answer:
<h3>3/20*200</h3>
=5*3
=15%
the percentage of the number is 15%
1/4 of the population is A+
if you wanted 5/9 to have that blood type you would need to make an equation using 1/4 and 5/9.
5/9 x 1/4 = 5/36 or 0.139
You can verify because of all 9 had the A+ you can do the same equation but with 9/9 and 1/4
9/9 x 1/4 = 9/36 which is 0.25 or 1/4
Answer:
The solution is (4, 1).
Step-by-step explanation:
For the first multiply the second equation by -1 then add them together.
4x + y = 5
-1( 3x + y = 3)
4x + y = 5
-3x - y = -3
x=2
Plug that in and you get -3 for y
Answer is (2,-3)
For the second, just add them
2d – e = 7
d + e = 5
3d=12
d=4
Plug that into either equation and e is 1
The solution is (4, 1).
First thing first, you have to use the proportion formula(is over of is a percent over 100).
Is=40
Of= n,
%= 30.
After setting that up and everything, your answer is 140.
