Scenario

Dean purchased a lawnmower from a local garden centre. The lawnmower cost $750, and he also purchased extra parts, which cost an additional $325. After using it twice, the lawnmower breaks. Dean contacts his local garden centre to make a complaint. After assessing the situation, the sales team at the garden centre believe that this is a faulty piece of equipment as the lawnmower is one of their best sellers. To retain Dean's custom, they offer to refund him for the lawnmower and the additional equipment, and offer him 10% off the lawnmower if he repurchases, as well as a further 5% off the additional equipment.

Referring to the scenario above, calculate how much the same lawnmower and the additional equipment would cost Dean at the new, discounted price. Show your workings below.
