Answer:
(Price x 0.20) + price
Step-by-step explanation:
To find a certain percentage of something, move the decimal on the percent 2 places to the left and multiply that by the original number
If something is marked up by a certain price, that means you’re adding to it so you just have to add whatever 20% of the item is to the original cost
Answer:
Step-by-step explanation:
The input value at which f(x) = g(x) can be found by setting the right sides of each of those equal to each other and solving for x.
1.8x - 10 = -4 and
1.8x = 6 so
x = 3 1/3
The bold equation is the answer to the first part, and the second part is that x = 3 1/3
For i=1 ===> Sum=4
for i=2===> Sum=2
for I=3===> Sum=1
Hence the answer is 7
Or you could have use the Sum formula of a GP:
Sum = a(1-r)^n/(1-r), with a=1, r=1/2 & n=3
