The correct answer is 15 years old. If Jim is currently 15 years old, then his dad is 60 years old. That means that in 10 years, Jim will be 25 and Dad will be 70. Seventy is equal to 25 times 2 plus 20.

nexus9112 [7]

Answer:

Since the question is partial, i will assume 2 scenarios:

They need to raise 1000 income

They need to make 1000 as profit

If $1000 as income:

Each ticket costs $15, so  tickets would bring them $1000 income. Fractional ticket is not possible, so rounding gives us 67 tickets as the answer.

If $1000 as profit:

Their cost of renting is $700. We know that .

So, . So, to raise $1700, we need  tickets. Fractional ticket is not possible, so rounding gives us 114 tickets as the answer.

ANSWER:

If need to raise atleast $1000 as income, they need to sell 67 tickets.

If need to raise atleast $1000 as profit, they need to sell 114 tickets.

The most probable answer would be 114 tickets

How do I write a percent as a fraction in simplest form and as a decimal
AlekseyPX
Take 37% as an example, just add a decimal point to the left 2 times. Decimal = .37. Fraction would be 37/100, because you cannot simplify.
