The way to solve this one - step equation is to divide by 50 on both sides to get x by itself :
50x=500
x = 10

Answer:
y = 156(0.82)x
Step-by-step explanation:
Since it is decreasing by 18% you need to subtract .18 from b (which equals 1) and it gives you 0.82.
Answer:
$128.40
Step-by-step explanation:
Find the total cost of the pizza before tax.
15 × 8 = 120
Set up a proportion to find the tax.
7/100 = x/120
Cross multiply
840 = 100x
Divide both sides by 100
Tax = $8.40
$120 + $8.40 = $128.40

Answer:
360 mg.
Step-by-step explanation:
The medicine has a decay rate of 40% in 25 hours, which means after 24 hours its amount will be 100% - 40% = 60% it's original value.
Let us call
the number of hours passed and
the number of 24-hours passed, then we know that
.
Now, the amount
of medicine left after time
(<em>d</em>th 24-hour) will be
![c = 1000(0.6)^d](https://tex.z-dn.net/?f=c%20%3D%201000%280.6%29%5Ed)
and since
, we have
![$\boxed{c = 1000(0.6)^{\frac{t}{24} }}$](https://tex.z-dn.net/?f=%24%5Cboxed%7Bc%20%3D%201000%280.6%29%5E%7B%5Cfrac%7Bt%7D%7B24%7D%20%7D%7D%24)
We now use this equation to find the final amount after
:
![c = 1000(0.6)^{\frac{48}{24} }](https://tex.z-dn.net/?f=c%20%3D%201000%280.6%29%5E%7B%5Cfrac%7B48%7D%7B24%7D%20%7D)
![c = 1000(0.6)^2 }](https://tex.z-dn.net/?f=c%20%3D%201000%280.6%29%5E2%20%7D)
![\boxed{c =360mg}](https://tex.z-dn.net/?f=%5Cboxed%7Bc%20%3D360mg%7D)
