Answer:

The bag costs 1500, while the umbrella cost 500

Step-by-step explanation:

Let the cost of the bag be b and the cost of the umbrella be u

Total cost is;

b + u = 2,000 •••••(i)

From the second part of the question;

b = 5u-1000 ••••••(ii)

Substitute ii into i

5u-1000 + u = 2000

6u = 2000 + 1000

6u = 3000

u = 3000/6

u = 500

To get b, substitute the value of u into equation ii

b = 5(500)-1000

b = 2500-1000

b = 1500

Scientific Notation is the way of writing a number or expressing them in a shorter or more compact way.

No, Taylor's resoning is incorrect because 2,800,000 = $2.8 * 10^{6}$

From the question, we are given:

2,800,000 .

2,800,000 in scientific notation is $2.8 * 10^{6}$ .

The reason the power is not to the negative 6 is that we are moving from the right-hand side to the left-hand side 6 times.

Therefore, Taylor's reasoning is incorrect.
