An account earns simple interest. Find the interest earned. $1200 at 2.8% for 30 months
sasho [114]

let's bear in mind that a year has 12 months, so 30 months is really 30/12 years.


\bf ~~~~~~ \textit{Simple Interest Earned}&#10;\\\\&#10;I = Prt\qquad&#10;\begin{cases}&#10;I=\textit{interest earned}\\&#10;P=\textit{original amount deposited}\dotfill & \$1200\\&#10;r=rate\to 2.8\%\to \frac{2.8}{100}\dotfill &0.028\\&#10;t=years\to \frac{30}{12}\dotfill &\frac{5}{2}&#10;\end{cases}&#10;\\\\\\&#10;I=(1200)(0.028)\left( \frac{5}{2} \right)\implies I=84

Marsha uses 8.5 pints of white paint and blue paint to paint her bedroom walls. 2/5
Serjik [45]

Answer:

5.1 pints

Step-by-step explanation:

Theres 2 ways

First way:

We can do 2/5 of 8.5 which is 3.4. Then, we can subtract 3.4 from 8.5 and get 5.1 pints.

Second way:

We can simply do 3/5 of 8.5 because the remaining 3/5 of the paint is blue. 3/5 of 8.5 is 5.1 pints

Hope this helped! I would appreciate a Brainliest if this helped you!

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.
