Katie wants to buy some popcorn for her family at the theater. Each small tub of popcorn costs $3 and each large tub of popcorn

Molodets [167]

For this case we propose a system of equations:

x: Represents the amount of small popcorn tubs

y: Represents the amount of large popcorn tubs

According to the data we have to:

$3x + 4y = 24$ (Spending all the money in your wallet)

$x + y = 7$ (Buying 7 popcorn tubs)

From the second equation we have:

$x = 7-y$

Substituting in the first equation:

$3 (7-y) + 4y = 24\\21-3y + 4y = 24\\21 + y = 24\\y = 24-21\\y = 3$

Thus, Katie can buy 3 large tubs of popcorn.

So:

$x = 7-3\\x = 4$

In addition, you can buy 4 small tubs of popcorn.

Answer:

3 large popcorn tubs.

4 small popcorn tubs.

If the population of a particular country is growing at 1.5 % compounded continuously, how long will it take the population to

DIA [1.3K]

$e^{0.015t}=3$
Taking natural logs of both sides, we get
0.015t=ln 3
t = ln 3/0.015 = 73.24

The answer is 73.24 years.
