First option is correct.
Step-by-step explanation:
Let amounts of money James may have after he sees Rita be x.
It is given that either James borrowed $12 from his friend Rita or she borrowed $12 from him.
So meeting Rita second time either he will $12 or he will receive $12.
The amounts of money James may have after second meeting with Rita is:
Case 1: If he pays $12.
.... (1)
Case 1: If he receives $12.
.... (2)
On combining equation (1) and (2), we get
Subtract 42.80 from both sides.
It can be written as
Therefore first option is correct.
Answer:
The approximate number of gallons consumed by a person in 2010 will be 4.9 gallons
Step-by-step explanation:
Recall that the formula for exponential decrease is given by a function of the form:
where A is the initial value, r is the rate of decrease, and x is the time elapsed.
In our case, the initial value of gallons of juice per person (at the starting time = 1981) is 16.5 gallons. So A = 16.5 gallons.
the rate of decrease "r" is the decimal form of: 4.1%, that is r = 0.041
So we have:
Now we can calculate what the average number of gallons would be in the year 2010, knowing that between 1981 and 2010 there is an elapsed time in years of: 2010-1981 = 29 years. Then:
