Doughnuts at one shop cost £1.80 each. Doughnuts at a second shop cost 15% more.
What is the difference in the cost of doughnuts at the two shops?

Given:

Cost of doughnut at one shop = £1.40

Unknown:

Difference in the cost of doughnuts at the two shops = ?

To find the difference in the cost of doughnuts at the two shops, we must know the cost of doughnut at the second shop;

 Given that the cost of doughnut at the other shop is 20% more;

      = 1.20 x £1.4

      = £1.68

The difference in the cost of doughnuts  = £1.68 - £1.40 = £0.28

So the answer is £0.28

If the donut cost 1.80 at the first shop it will cost 2.07 at the second shop. the difference is 27 cents

1.80×15%=.27

1.80+.27=2.07

answer: .64

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
