Answer:
3
Step-by-step explanation:
To find the rate of change we: divide the change in y (output) by the change in x (input).
A = (-3 - 0) / (0 - 1) = -3 / -1 = 3
:)
Use PEMDAS form. (Parentheses, exponents, multiplication, division, addition, subtraction.) You will first solve -2-8 which is -10, then finish with 9 + (-10), or 9-10, which is -1. The answer is -1.
C.P. = $95000
S.P. = $280000
a. Profit
= S.P. - C.P.
= $280000 - $95000
= $185000
b. Let the profit% of C.P. be x.
(x/100) × $95000 = $185000
=> x/100 = $185000/$95000
=> x/100 = 37/19
=> x = (37/19) × 100
=> x = 3700/19
=> x = 194 14/19
So, profit percent of buying price is 194 14/19%.
c. Let the profit% of S.P. be x.
(x/100) × $280000 = $185000
=> x/100 = $185000/$280000
=> x/100 = 37/56
=> x = (37/56) × 100
=> x = 3700/56
=> x = 925/14
=> x = 16 1/14
So, profit percent of selling price is 16 1/14%.
d. Buying price percentage profit sounds better as far as Ella is concerned.
