Hi there!
3/4 of sugar is needed for 6 servings.
1/8 x 6 = 6/8 simplify it and you get 3/4.
So 3/4 is your answer.
Hope this helps ;D
The total should be 287.59. You add the numbers (127.12+94.50+65.97) and it should equal to that.
Answer:
Let the 'cart' total is x and total payment is y.
The sales tax is 5.6% added to the 'cart' amount and then shipping and handling fee added.
<h3>Part A</h3>
<u>There are three intervals as below and function added accordingly:</u>
- 0 < x ≤ 49.99 ⇒ y = x + 5.6% + 3.95 = 1.056x + 3.95
- 50 ≤ x ≤ 75.99 ⇒ y = x + 5.6% + 11.95 = 1.056x + 11.95
- x ≥ 76 ⇒ y = x + 5.6% + 5.95 = 1.056x + 5.95
<h3>Part B</h3>
- x = 74.50, this falls in the second interval
- y = 74.50*1.056 + 11.95 = $90.62 (rounded )
<h3>Part C</h3>
y = 89.20, this is close to the number we got in part B and we assume it is same - the middle interval.
- 89.20 = 1.056x + 11.95
- 1.056x = 89.20 - 11.95
- 1.056x = 77.25
- x = 77.25 / 1.056
- x = 73.15 (rounded )

X^2+2x-5x-10
x(x+2)-5(x+2)
(x-5)(x+2)
136 /5.5 = 24.73 so every 1 inch on the map is around 24.73 miles
24.73 * 0.75 = 18.55
he is about 18 1/2 miles away
