a. $10.50

b.$24.50

c.3/100 or 3%

Step-by-step explanation:

The sweater is 70% off, so first find 70% of 35. Do that by multiplying 0.7 by 35.

0.7x35=24.5

Then subtract 24.5 from 35.

35-24.5=10.5

Question 1 a: $24.5 b: $10.5 c: 3/10

Step-by-step explanation:

A: 7/10 = 0.7

0.7 * 35 = 24.5

B: $35 - $24.5 = $10.5

C: Since it is 7/10 of the normal cost, you save 3/10.

Checking the work: 3/10 = 0.3

0.3 * 35 = 10.5, or the amount you saved.
