In a sale, a clothes shop reduces its price by 15% a shirt usually cost �39 how much is it in the sale?
-----
Let x be the sale price:
Equation:
x = 39 - 0.15*39
x = 0.85*39
x = L33.15
======================
In a sale, a clothes shop reduces its price by 15% a jacket usually cost �88 how much is it in the sale
x = 0.85*88 = L74.80
======================
The boss gives all his employees a 3% pay rise Paul used to earn �11 an hour how much does he get after the rise?
x = 1.03*11 = L11.33
======================
The boss gives all his employees a 3% pay rise
Sandy used to earn a salary of �11850 how much does she get after the rise?
x = 1.03*11850 = L205.50
=======
