Apala has Rs 200 with her, and she spent 80% from the amount she had. Calculate the money left with her.
(a)Rs 20
(b) Rs 10
(c) Rs 40
(d) Rs 30

PLS help I can't at all solve this pls soon as possible

I guess answer is Rs 40

Hope it help you

40

Step-by-step explanation:

we make assumption that 200 is 100% since it is our output value

We next represent the value we seek with x

From step 1, follows 100%=200

in the same x%=200

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
