20%.
As you can see, he gained 25 dollars within the past month.
There is a simple formula for this.
Increase = New number - original number. Then divide your answer by the original number and multiply by a hundred.
150 - 125 = <u>25</u>
25/125 = <u>0.2</u>
0.2 * 100 = 20%
the total of the meal costs $29.46
the sales tax is $1.77
the tip is $4.69
so the total cost is $35.92
C is your correct answer on this one
Answer:
Step-by-step explanation:
This is a parallelogram. What we know about the diagonals is that they intersect each other at their midpoints. In other words, QT = ST, and PT = RT. So that gives us 2 equations:
If QT = ST, then
2x = y + 3
If PT = RT, then
x + 5 = y Solving by substitution, plug x + 5 in for y in the first equation.
2x = x + 5 + 3 and
2x = x + 8 and
x = 7 Now plug in 7 for x to solve for y:
If x + 5 = y, then
7 + 5 = y and
y = 12
