Compute the total cost of the meal to the nearest cent: meal costs $24.62 plus 6% tax and 15% tip.​
matrenka [14]

The total cost of the meal is $30.02

Step-by-step explanation:

Given,

Cost of meal = $24.62

Tax = 6%

Tax amount = 6% of cost of meal

Tax\ amount=\frac{6}{100}*24.62\\Tax\ amount=\frac{147.72}{100}\\Tax\ amount=\$1.48

Cost after sales tax = 24.62+1.48 = $26.10

Tip = 15%

Tip amount = 15% of cost after sales tax

Tip\ amount=\frac{15}{100}*26.10\\\\Tip\ amount=\frac{391.5}{100}\\Tip\ amount=\$3.92

Total cost of meal = Cost after sales tax + Tip amount

Total cost of meal = 26.10+3.92 = $30.02

The total cost of the meal is $30.02

Keywords: percentage, sales tax

Find the slope and y-intercept of 3y - 4x = 39
Alexus [3.1K]
<h2>Greetings!</h2><h3>Firstly, the slope is found by rearranging the formula:</h3>

3y = 4x + 39

y = \frac{4x}{3} + \frac{39}{3}

When x is 0, y = 0(x) +  \frac{39}{3}, so the y intercept is \frac{39}{3}

<h3>Next, the slope is simply the number in front of the x, </h3>

So  \frac{4x}{3} can be rearranged to  \frac{4}{3}x, so the slope would be \frac{4}{3}.


<h2>Hope this helps!</h2>
