Because of inflation, $1 you will have in the future will be worth

Let's assume that you have 40 years left to live. As a starting point, let's also assume that average annual inflation rate will be 2% over that period.

You can figure out how much $1 in 40 years is worth today by doing simple present value calculation:

PV = FV / (1+average annual inflation rate)^# of years

Now plug in the assumptions,

PV = $1 / 1.02^40 = $1 / 2.2080 = $0.45

This means that in 40 years $1 will buy you the same amount of goods and services as $0.45 buys today, i.e. you'll be able to mail a letter in the US.

remember these are a guess using these specific numbers hoped this helped

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
