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?
2 answers:
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.
Answer: The tennis racket costs $84.
Step-by-step 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.
