Tonya bought gifts for her family that cost $25, $14, $33, and $19. She has to buy one more gift and wants her mean cost to be $
Brums [2.3K]

____________________________________________________

Answer:

Your answer would be $34.

____________________________________________________

Step-by-step explanation:

In order to get the mean cost that she wants from the gift, we would need to get the numbers that we already had, and have another set of row with the amount of gifts she needs with the mean she wants.

Here is how it should look like:

$25  $14  $33  $19    x

$25  $25  $25  $25 $25

We are trying to find the number for "x"

Therefore, we would need to use the process of adding, then subtracting after.

Lets add:

25+14+33+19=91\\\\25+25+25+25+25=125

What we would do now is subtract the numbers in order to get the price that Tonya wants from her gift, if she buys another gift.

125-91=34

Tonya should spend $34 on her last gift.

$34 should be your FINAL answer

ANSWER PLEASE PLEASE PLEASE
Vaselesa [24]
$24.50 is your original amount, and you know you have a 20% added to that. So, you can multiply the money by the percentage:

24.5 x 1.2 (we multiply it by 1.2 because we want the tip PLUS the original amount)
= 29.4

So the answer is the first choice, $29.40
