1.  = 2 (1/4 + x) = 1/2 + 2x

2.  = (3y - 2)/ 3  /    (5y+ 1) / 5
     = (3y - 2)/ 3   * 5 / (5y + 1)
     =   15 / (3y - 2)(5y + 1)
     = 15 / 15y^2 - 7y - 2)

3.   = (a + bc) / b  *  b / a - bc

       =  (a + bc) / (a - bc)

4.  = (2a + 1) / a  *  a / (2 - a^2)
      =  (2a + 1) / (2 - a^2)

5.   =  (3x +2x) / 6 * 4 / x
      =  5x / 6 *  4 / x
       =   5*4 / 6
        = 10 / 3

4) Arnold ate breakfast at a restaurant. His total came to $76.75. There is an 8% sales tax and 15% tip. What is Arnold's total
lisov135 [29]

Answer:

The total cost is $95.32.

Step-by-step explanation:

Given:

Total came to $76.75. There is an 8% sales tax and 15% tip.

Now, to find the total cost.

<em>8% sales tax is there so we calculate the amount after adding sales tax:</em>

$76.75 + 8% of $76.75

76.75+\frac{8}{100}\times 76.75

76.75+0.08\times 76.75

76.75+6.14

82.89

The cost after sales tax is $82.89.

Now, <em>the cost after 15% tip:</em>

$82.89 + 15% of $82.89

82.89+\frac{15}{100}\times 82.89

82.89+0.15\times 82.89

82.89+12.43

95.32

The cost after the tip is $95.32.

Therefore, the total cost is $95.32.
