To solve this - lets work in smaller steps.

• We have an item that costs $995. Lets first find 10% of this amount. If we remember that 10% of any number is the number itself minus a zero, we can save ourselves the hassle of needing calculators.

• 10% of 995 is 99.5.

• 20% of 995 would be 99.5 x 2 or 199.0

• Since most cash registers will round up to the nearest percentage you'll rarely find something 24% off, it'll most commonly be 25% off.

• Now we need 5% of 995 which would be 1/2 of 99.5 or 10%. So 5% would be 49.75.

• Add our percentages together and subtract them from the purchase price.

99.5 (10%) + 99.5 (10%) + 49.75 (5%) = 248.75.

• Now subtract 248.75 from the purchase price.

995 - 248.75 = 746.25.
