A book club wants to raise $5,000 during a dinner fundraiser. The club members have sold 323 adult dinners at $10.75 each. The cost of a child dinner is $5.50. How many child dinners will they need to sell to reach their target amount?

Answers

Answer 1

Answer:

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sod

Step-by-step explanation:

Answer 2

Money earned from adult dinners = 323 x 10.75 = $3472.25
Money required to reach target amount = 5000 - 3472.25 = $1527.75
No. of child dinners required to reach the target amount = 1527.75 / 5.50 = $277.8
Therefore, 278 child dinners are needed to reach their target amount

$54,000 - $6,750 = $47,250 is the price of the next model

Step-by-step explanation:

The current model costs 35000$
12.1% of 35000$= 4235$
The price will be decreased by 4235$
The next model of the car’s price will be

A group of students were surveyed about which type of party they would most want to attend.

boy | girl | total
bowling: 9 6 15
painting: 15 10 25
skating: 6 14 20
total: 30 30 60

What is the experimental probability that the next student randomly selected will be a boy who would most want to attend a skating party?

Answers

Answer:

10%

Step-by-step explanation:

first, we need to know how many boy would attend the skating party. the number is 6. Now, to find the probability, we need to use the percent that 6 is of the total. if we look at the bottom of this table, we see the total people surveyed is 60 people. now, since 60/6=10, 6 is 10 percent of 60. the probability is therefore 10%

A man is trying to zombie-proof his house. He wants to cut a length of wood that will brace a door against a wall. The wall is 4 feet away from the door, and he wants the brace to rest 2 feet up the door. About how long should he cut the brace?

Answers

Answer:

Assuming you're rounding to the nearest tenth, he should cut the brace 4.5 feet long.

Step-by-step explanation:

Since this is a right triangle, you can use the a^2 + b^2 = c^2 easily.

You can use either 2 or 4 as the a or the b.

After filling in the equation, 2^2 + 4^2 = c^2, you can calculate it to find it is 4 + 16 = c^2.

If you add 16 + 4, you get 20. So now, you need to find the square root of 20 which is 4.4721 but if you round to the nearest tenth, you get 4.5^2.

He should cut the brace to 4.5 square feet.

I hope this helps :))

Divide 1024 by its half and keep dividing every number by its half and that is how you solve it
