sergij07 [2.7K]
<h3>Total cost of their lunch, including the tip is $ 27.6</h3>

<em><u>Solution:</u></em>

The cost for Dana and Courtney's lunch is $24

They want to leave a  15% tip

To find:  total cost of their lunch, including the tip

<em><u>Find the tip amount</u></em>

Tip amount = 15 % of 24

Tip\ amount = \frac{15}{100} \times 24\\\\Tip\ amount = 0.15 \times 24\\\\Tip\ amount = 3.6

<em><u>what is the total cost of their lunch, including the tip?</u></em>

Total cost = cost of lunch + tip amount

Total cost = 24 + 3.6

Total cost = 27.6

Thus total cost of their lunch, including the tip is $ 27.6

How do I solve this?
laila [671]
The < is just like and equal sign just looks a little different think of it that was for the first couple steps. So you have 13-3y<-5. First do, -5+13=8. Now you have -3y<8. Then your want to do 8 divided by -3 and you get=-2.666666667 and that equals y.

-2.7=y then make that equal sign into the normal sign again. -2.7
