Answer 1

Dominic receives 12 pounds on an item whose usual price is 80 pounds

Write an equation that represents the amount of discount offered (d) on an item whose usual price is p.

The given parameters are:

Discount =15%

Price = p

Amount of discount = d

The equation that represents the amount of discount offered (d) on an item whose usual price is p is

d = Discount * p

This gives

d = 15% * p

Evaluate

d = 0.15p

How much discount does Dominic receive on an item whose usual price is 80 pounds,

In (a), we have

d = 0.15p

Here, p = 80

So, we have

d = 0.15 * 80

Evaluate

d = 12

Hence, Dominic receives 12 pounds on an item whose usual price is 80 pounds
