Answer:

<em>a:b:c=8:12:15</em>

Step-by-step explanation:

<u>Combined Ratio</u>

We are given the ratios:

a:b=2:3

b:c=4:5

The combined ratio a:b:c will include all three variables in one single expression.

Before finding it, we must have a common number for the common variable (b). Since b is 3 in the first ratio and 4 in the second ratio, we must equate both by finding the LCM of 3 and 4=12, thus both ratios will be amplified as follows:

a:b=2:3=(2*4):(3*4)=8:12

b:c=4:5=(4*3):(5*3)=12:15

Now there is a common factor in both ratios, we can combine them removing the common factor:

a:b:c=8:12:15

The following list shows the items and prices for a restaurant order. Calculate the total amount if there is an 8% tax and the c
Andreas93 [3]

Answer:

Option B

The total amount is $63.31 if there is an 8% tax and the customer leaves a 20% gratuity.

Step-by-step explanation:

Given:

List of items                           Prices

1 Appetizer                             $8.59

2 Entrees                                $15.99 each

1 dessert                                 $4.69

2 drinks                                   $2.10 each

Total amount for the food order came to, \left ( 1\times \$ 8.59 \right +2\times \$15.99+1\times \$4.69+2\times\$2.10)=\left (\$ 8.59 \right + \$31.98+ \$4.69+\$4.20)=$49.46

Since the restaurant charges 8% as a tax on the total bill.

First, figure out the tax, 8% of $49.46=0.08\times $49.46=$3.9568

Now, figure out the Customer leaves a  gratuity, 20% of $49.46=0.20\times \$49.46=\$9.896

The total amount( including 8% tax and 20% gratuity )=$49.46+$9.896+$3.9568=$63.3128\approx \$63.31
