1 answer:

4 0

let x = # of adult tickets sold, thus the # of children tickets = 70-x 7.5x + 5(70-x) = 450 ^ 7.5x + 350 -5x = 450 ^ 2.5x = 450-350= 100 x = 40 adults tickets thus 70—40 = 30 children tickets

mel-nik [20]

Answer:

Step-by-step explanation:

The average is the total of the scores divided by 5.

128 x 5 Gives us the total scores of 640. I know that one bowler had a score of 160. I will subtract that from the total of 640. 640-160 = 480. Since the 4 bowlers left, all had the same score, I will divide 480 by 4 to get 120

Kraig deposited money into a money market account. It has an interest of 12% and is compounded annually. Kraig thought 3% would

Klio2033 [76]

Answer:

If the amount is P, with the interest rate of 12%, the interest over the year is:

P*(1.12) - P = 0.12P

In this case the quarterly interest rate is:

0.12P/4 = 0.03P

With the same amount and 3% quarterly rate, the yearly interest would be:

P*(1.03)^4 - P = 0.1255P

The quarterly interest rate in this case is:

0.1255P/4 = 0.031375P

If the quarterly interest rate is r, it should be little less than 3% to yield a 12% yearly rate.

So Kraig is wrong.
