There is a very simple way of dealing with percentages.
"increase" means add
"decrease/discount/reduce" means subtract
Now, we know that the original price is 100%.
100% = 1 (like 50% = 0.5)
So if an object's price is x and it is 20% off, we get:
100%x - 20%x
Taking x common,
x(100% - 20%)
= 0.8x
Therefore, if we fist add/subtract the percentages we can multiply directly with the original to get the answer. This is as follows:
5] Increase 101 by 16%
1 + 0.16 = 1.16
So the answer is:
101 * 1.16
= 117.16
6] Decrease 36 by 21%
1 - 0.21 = 0.79
The answer is:
36 * 0.79
= 28.44
7] Let original price be x, we know it is 35% off
1 - 0.35
= 0.65
0.65x = 13
x = 20
Answer:
The equation is in the form 268 = L + 225 and the points of left - handed shots are 43 .
Step-by-step explanation:
As given
Eloise scored a total of 268 points during the basketball season.
Of her total points, L points came from left-handed shots.
She scored 225 points with right-handed shots.
Than the equation becomes
Total points = Left handed points + Right handed points
268 = L + 225
Solving the equation
L = 268 - 225
L = 43
Therefore the equation is in the form 268 = L + 225 and the points of left - handed shots are 43 .
