Answer:

Market price $400

Cost price $300

Step-by-step explanation:

MP: market price

CP: cost price

1. (MP x 0.9) - CP = 60

CP = 0.9MP - 60

2. MP - CP = 100

CP = MP - 100

0.9MP - 60 = MP - 100

MP - 0.9MP = 100 - 60

0.1MP = 40

MP = 400

Cost price = MP - 100 = 400 - 100 = 300

190 = 200^b, make b the subject

MArishka [77]

Answer:

b = $\frac{ln190}{ln200}$

Step-by-step explanation:

Using the rule of logarithms

log $x^{n}$ ⇔ nlogx

Given

190 = $200^{b}$ ( take the natural log ln of both sides )

ln190 = ln $200^{b}$ = bln200 ( divide both sides by ln200 )

$\frac{ln190}{ln200}$ = b
