Question

Becca has saved 25% of the money that she needs to buy a new tennis racket. If she has saved $21 jow much money does the tennis racket cost?

Answer 1

Answer: The tennis racket costs $84.

Explanation:

Hi, to answer this question we have to write an equation.

The price of the tennis racket (x) multiplied by the percentage Becca saved in decimal form (25/100= 0.25) is equal to $21.

Mathematically speaking:

x (25/100) =21

Solving for x:

x 0.25 = 21

x =21/0.25

x = $84

The tennis racket costs $84.

Feel free to ask for more if needed or if you did not understand something.

Answer 2

Let x be the entire portion of the money Becca needs to save to buy a new tennis racket.

So, 0.25x=$21

x=$21/0.25
x=$84

Thus, the total amount she needs to save is $84. Now, we'll deduct 25 from 84 to get the 75 percent or the remaining amount she has to save.

$84-$21=$63

The answer is $63.
