Kierston needs to paint a wall of the youth center. She knows that 1 can of paint covers an area of 2.2 square meters. Kierston

Step2247 [10]

Answer:

See Explanation

Step-by-step explanation:

Given

$1\ can = 2.2m^2$

Required

Determine the number of cans for the wall

The dimension of the wall is not given. So, I will use the following assumed values:

$Length=20m$

$Width = 44m$

First, calculate the area of the wall

$Area = Length * Width$

$Area = 20m * 44m$

$Area = 880m^2$

If $1\ can = 2.2m^2$

Then $x = 880m^2$

Cross Multiply:

$x * 2.2m^2 = 1 * 880m^2$

$x * 2.2m^2 = 880m^2$

$x * 2.2 = 880$

Make x the subject

$x = \frac{880}{2.2}$

$x = 400$

400 cans using the assume dimensions.

So, all you need to to is, get the original values and follow the same steps

natka813 [3]

Answer:

The gain is of $17.50

Step-by-step explanation:

When you buy the bond the exchange rate is $1.50 = £1.

You pay £45 = $1.50\times45$ =$67.50 for the British bond.

No, you sell the bond for £50 and the exchange rate is $1.70 = £1.

So, you earned $50\times1.70=85$ dollars

Your gain is $85-67.50$ = $17.50
