Katy buys ‘x’ cakes.

Mathematics
1 answer:
Viktor [21]3 years ago
5 0
Answers:
Katy bought 12 cakes
Gugu bought 36 cakes
Deanna bought 14 cakes

Explanation:
We are given that:
Katy bought x cakes 
Gugu bought 3 times as many as Katy. This means that Gugu bought 3x cakes
Deanna bought 2 cakes more than Katy. This means that Deanna bought x+2 cakes

Total number of cakes bought = x + 3x + x + 2 = 5x + 2 cakes

We know that the price of each cake is 85 p = £0.85 and that the total amount paid is <span>£52.7
This means that:
(5x+2)(0.85) = 52.7
4.25x + 1.7 = 52.7
4.25x = 52.7 - 1.7
4.25x = 51
x = 51 / 4.25
x = 12

Now, we will get the number of cakes that each bought as follows:
Katy bought x cakes = 12 cakes
Gugu bought 3x cakes = 3(12) = 36 cakes
Deanna bought x+2 cakes = 12 + 2 = 14 cakes

Hope this helps :)</span>

Find the average rate of change of the function f(x)=(3/-3x-5), on the interval x ∈ [0,3]
Svet_ta [14]

Answer:

The average rate of change on the given interval is 9/70

Step-by-step explanation:

Here, we are to find the average rate of change of the function on the given interval

We proceed as follows;

on an interval [a,b] , we can find the average rate of change using the formula;

f(b) - f(a)/b-a

From the question;

a = 0

b = 3

f(0) = -3/5

f(3) = -3/14

Substituting the values, we have;

-3/14-(-3/5)/3-0

= 3/5-3/14/3

= (42-15)/70/3

= 27/70/3

= 27/70 * 1/3 = 9/70
