Question

Help me and show work

Answer 1

She paid $29.29

Explanation:

Finding 7% of 25

Y is 7% of 23.2

Solving our equation for Y

Y = P% * X

Y = 7% * 23.2

Converting percent to decimal:

p = 7%/100 = 0.07

Y = 0.07 * 23.2=1.624

Y ≅ 1.62

Finding 18% of 25

Y is 18% of 23.2

Solving our equation for Y

Y = P% * X

Y = 18% * 23.2

Converting percent to decimal:

p = 18%/100 = 0.18

Y = 0.18 * 23.2= 4.176

Y≅4.18

Add sales tax and tip to 25

25+4.18+1.62= 30.8

But since my answers were estimated to a different way, I would say it s best to say it is d.29.29
