Yolanda is saving for a new cell phone. So far she has saved $54 from her babysitting jobs. She calculated that this is 45% of the amount she needs for the phone. What is the total cost of the new cell phone?

$120

To find the total cost of the new cell phone, we need to determine the amount that corresponds to 100% of what Yolanda needs for the phone. We know that the $54 she has saved is 45% of the total amount.

To find the total cost, we can set up a proportion using the given information:

45% (or 0.45) represents $54.

Let's set up the proportion:

0.45 / 1 = $54 / x

To solve for x, we cross-multiply and simplify the expression:

0.45 * x = 1 * $54
0.45x = $54

Now, we will isolate x by dividing both sides of the equation by 0.45:

x = $54 / 0.45
x ≈ $120

Therefore, the total cost of the new cell phone is approximately $120.
