Answer:

a. 24.5 $

b. 10.5 $

c. 7/10

Step-by-step explanation:

Given the original price of the sweater is: $ 35.

a) If you pay only $\frac{7}{10}$ of the price, then the actual amount paid is: $\frac{7}{10} \times 35 = \frac{49}{2}$ = 24.5 $.

b) Total amount Saved = Actual price - Price you paid

$\implies$ Total Amount Saved = $35 - \frac{49}{2}$

$= \frac{21}{2}$ = 10.5 $.

c) Fraction of the original price saved = Total amount Spent/Actual Price

$\implies$ Total amount Saved = $\frac{49}{2(35)}$

$= \frac{49}{70}$ = $\frac{7}{10}$
