A zoo has an equal number of African elephants and Asian elephants. The African elephants cost £11 per day to feed and the Asian elephants cost £9 per day to feed. The total daily bill for feeding all of the zoo's elephants is £1000. How many elephants does the zoo have?

The zoo has 50 African elephants and 50 Asian elephants which means that there are 100 elephants.

Step-by-step explanation:

From the information provided, you can say that the result of adding up the African elephants cost to feed per day for the number of African elephants plus the Asian elephants cost to feed per day for the number of Asian elephants would be equal to £1000, which can be expressed as:

11x+9y=1000, where:

x is the number of African elephants

y is the number of Asian elephants

Now, as the statement indicates that the zoo has an equal number of African elephants and Asian elephants, this means that x=y and you can replace y with x and solve for x:

11x+9x=1000

20x=1000

x=1000/20

x=50

According to this and considering that the zoo has an equal number of African elephants and Asian elephants, the answer is that the zoo has 50 African elephants and 50 Asian elephants which means that there are 100 elephants.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
