A coat has an original price of $48.99. Gloria wants to calculate the final cost of the coat including the 7% sales tax. She could use the expression 0.07 (48.99) + 48.99 to determine the final cost. Which other express could she also use to determine the final cost?

(0.07) ($48.99)
(1.07) ($48.99)
(1.93) ($48.99)
(0.93) ($48.99)

Answer (1.07)(48.99)
Ex
Since the first expression was
(0.07 x 48.99) + 48.99
Then multiply 0.07 by 48.99 =3.4293 + 48.99 = 52.4193

Try

1.(0.07)(48.99) =3.4293

2.(1.07)(48.99)=52.4193

3.(1.93)(48.99)= 94.5507

4.(0.93)(48.99)= 45.5607


The equation 2 was the only one that had the Sam answer as 52.4193


I hope this helped :)
