The sum of two numbers is 16. their difference is 1. what is the product of the two numbers

The product of the numbers is 63.75

Step-by-step explanation:

Let the numbers be x and y

x + y = 16

x -y = 1

Adding both together

2x = 17

x = 17/2

x = 8.5

Recall

x -y = 1

8.5 - y = 1

y = 8.5 - 1 = 7.5

Their product is xy

so we have 7.5 * 8.5 = 63.75

£13.73

Step-by-step explanation:

3% of £2100 is £63

To get her average pay per hour in 2017, we have to multiply her £2163 monthly salary by 12,

2163 x 12 = 25956

Total hours worked in 2017 is 42 x 45 = 1890

So hourly rate for 2017

= 25956 / 1890

= 13.73
