26%

d

Answer 1

35.191083%

Explanation:

12.56/100=0.1256 (1%)

That's one percent of 12.56. How much by 0.1256 (1% of 12.56) is 16.98 (rised price)?

I used a two-step equation to get the answer

• x*0.1256 = 16.98
• /0.1256 /0.1256

Divide both sides to get

• x = 135.191083

Now just subtract 100 because that was the old value

• 135.191083 - 100 = 35.191083

and you get 35.191083. Therefore, the answer is D.

Answer 2

A

Explanation:

`(16.98 - 12.56)/(16.98) * 100 = 26`
