The ratio of Beatriz, Hannah, and Julia's savings are 7:12:18. The three girls have a total savings of $111. How much more money has Julia saved than Beatriz? I NEED THE ANSWER ASAP!!!!!!!

Well, well, well, let's calculate this with a smile! To find out the difference between the savings of Beatriz and Julia, we need to determine how many "parts" they differ by.

Since the ratio of Beatriz, Hannah, and Julia's savings is 7:12:18, we can add up these parts to get 7+12+18=37 parts in total.

Now, we know that the total savings is $111, which means that each part of the ratio is worth $111/37=$3.

Julia's savings is 18 parts, which translates to 18*$3=$54.

Beatriz's savings is 7 parts, equal to 7*$3=$21.

So, Julia has saved $54 - $21 = $33 more than Beatriz.

To find the difference in savings between Julia and Beatriz, we first need to determine the savings of each girl individually.

Let's assign variables to represent their savings:
Let B be the savings of Beatriz,
Let H be the savings of Hannah, and
Let J be the savings of Julia.

According to the given ratio, the savings are in the ratio of 7:12:18.
This means that the ratio of B:H:J = 7:12:18.

We can set up an equation using this ratio:
7x + 12x + 18x = 111
where x represents the common multiplier.

Simplifying the equation, we have:
37x = 111

Dividing both sides of the equation by 37, we get:
x = 3

Now, we can find the individual savings:
B = 7x = 7 * 3 = $21
H = 12x = 12 * 3 = $36
J = 18x = 18 * 3 = $54

To find the difference between Julia's and Beatriz's savings, we subtract their savings:
J - B = $54 - $21 = $33

Therefore, Julia has saved $33 more than Beatriz.

To solve this problem, we need to find out the individual savings of Beatriz and Julia.

step 1: Add up the ratio numbers to find the total number of parts.
7 + 12 + 18 = 37

step 2: Divide the total savings by the total number of parts to determine the value of one part.
$111 / 37 = $3

step 3: Multiply the value of one part by the ratio for each person to find their individual savings.
Beatriz's savings = 7 parts * $3 = $21
Julia's savings = 18 parts * $3 = $54

step 4: Calculate the difference between Julia's and Beatriz's savings.
$54 - $21 = $33

Therefore, Julia has saved $33 more than Beatriz.

let their savings be 7x, 12x, and 18x

then: 7x + 12x + 18x = 111
solve for x, then sub back into the above definitions.
