To solve first move the 98 to the other side by subtracting it from both sides. Then divide by - 1 on both sides to that the x^2 is no longer a negative. You are left with:

x^{2} = 98

Now square root both sides to get

x = +/-  \sqrt{98}

The two factors that make up 98 are 49 and 2. 49 can be square rooted. So we are left with these answers:

x = - 7 \sqrt{2} and x = 7 \sqrt{2}

1.<br> What is the unit price of shampoo if a<br> 15-ounce bottle costs $2.79?
Rama09 [41]

Answer:

  • $2.79 per bottle
  • $0.186 per ounce

Step-by-step explanation:

When you talk about "unit price," you need to define the unit of interest. Unit prices on grocery store shelves don't always use the same unit, even for like items. Here it might be convenient to use any of the following as the "unit":

  • 1 bottle
  • 1 ounce
  • 1 pint (16 ounces)
  • 1 cup (8 ounces)

The "unit price" is computed as ...

  unit price = (price for some number of units)/(the number of units)

The "number of units" may be larger, smaller, or equal to 1.

Then the price per cup (8 ounces) would be ...

  unit price = (price for 15 oz)/(15/8 cups) = ($2.79)(8/15)

  = $1.488 per cup

__

The price per ounce would be ...

  unit price = ($2.79)/(15 oz) = $0.186/oz

__

We assume that the unit of interest is probably 1 ounce, but it could be something else. Your grader may expect the value to be rounded to the nearest cent, $0.19 per ounce.
