Emily took 300 US dollars to the bank to exchange it for Canadian dollars. The exchange rate on that day was 1.25 Canadian dolla
Paha777 [63]

Emily wanted to exchange her 300 US Dollars for Canadian Dollars.

The exchange rate for it was 1.25 Canadian Dollars for 1 US Dollar.

This means that 1 US Dollar = 1.25 Canadian Dollars.

So if we were to follow this pattern,

2 US Dollars = 2 × 1.25 = 2.5 Canadian Dollars

3 US Dollars = 3 × 1.25 = 3.75 Canadian Dollars

4 US Dollars = 4 × 1.25 = 5 Canadian Dollars

So for 300 US Dollars, we'll need to multiply 300 by 1.25.

300 US Dollars = 300 × 1.25 = 375 Canadian Dollars.

Hope it helps. :)

Question:<br> Image Below
konstantin123 [22]

Answer:

The answer will be: C: 2<em>t </em>+ 10

Step-by-step explanation:

You can check the answer by replacing <em>t </em>with any number.

Example:

I want to find the perimeter for 3 triangles. Here's how I would write the equation.

2(3) + 10 = 6 + 10 = 16

We can check by adding all the sides for three triangles.

2 + 2 + 2 + 5 + 5 = 16

Hope this helped :)
