Answer:

5

Step-by-step explanation:

Let the number of kids be x

We are given that she charge $25 per day per child

So, she charge for x kids per day = $25x

So,charge for x kids for 20 days = 20 \times 25 x = 500x

Her expenditure per day per kid is of $5

So, her expenditure per day for x kids = $5x

So, her expenditure 20 days for x kids =  20 \times5 x = 100x

So, she gained for taing care of x kids for 20 days = 500x-100x = 400x

Since we are given that her target is to earn $2000

So, A.T.Q

400x= 2000

x= \frac{2000}{400}

x=5

Hence the minimum number of kids she has to watch per weekday that month is 5

solniwko [45]

Answer:

Bola is 8 years old.

Step-by-step explanation:

Let Bola's age be x

Dada's age be y

Ayo's age be z

If the sum of ages of Bola, Dada and Ayo is 32 years, then;

x + y + z = 32

If they share a sum of money in ratio of their ages, then the ratio of their ages will be x : y : z

Also if Bola gets N400, Dada get-N400 and Ayo get N800, then the total amount of money shared will be expressed as:

T = 400 + 400 + 800

T = N1600

Next is to get the age of Bola

\frac{age \ of \ bola}{32}* Total \ amount \ shared = Bola's \ Share

Substitute the required variables and values into the formula;

\frac{x}{32}*1600= 400\\50x=400\\x=\frac{400}{50}\\x=8

This shows that Bola is 8 years old
