Bao has an original oil painting worth 30{,}00030,00030, comma, 000 Chinese Yuan. Each year the painting's value increases by 15\%15%15, percent.
Which graph best represents the relationship between time and the painting's value?

The graph in the attached figure

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

where

y is the painting's value

x is the time in years

a is the initial value

r is the rate of change

we have

substitute

using a graphing tool

The graph in the attached figure

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

a. is correct
