valkas [14]

Answer:

Cornor has $14.17 initially

Step-by-step explanation:

The complete question is as follows

Connor has five times as much money as Jayden. Connor gives some money to Jayden. They now have £8.520each. How much did Connor have at the start?

solution

In this question, we are concerned with knowing how much that both had initially.

Let the amount of money Jayden has be £x . Since Cornor has Five times this, he has £5x

Let the amount of money Cornor gave Jayden be £y.

This means ;

5x - y = 8.50 .....(

(i)and also x + y = 8.50 ......(ii)

It is this equations we solve simultaneously

From i, we can say let y= 5x - 8.50, and we insert this into equation ii

x + 5x - 8.50 = 8.50

6x = 17

x = 17/6

x = $2.83

y = 5x - 8.50

y = 5(2.83) - 8.50

y = $5.67

The amount of money Cornor has at first is 5x = 5(17/6)

5x = $14.17
