A lamp that normally sells for $35 is on sale for
35% off. How much will the lamp cost after a 8%
sales tax?

Find 35% of 35. First, turn 35% into a decimal by dividing by 100.

35% ⇒ 0.35

Now multiply 0.35 by 35.

35 × 0.35 = 12.25

Subtract 12.25 from 35 to find the discounted price of the lamp.

35 - 12.25 = 22.75

Now find the amount of sales tax by repeating the first two steps but with 8% and 22.75.

8% ⇒ 0.08

Multiply 0.08 by 22.75.

22.75 × 0.008 = 1.82

The tax is $1.82, now we need to add it to 22.75.

22.75 + 1.82 = 24.57

The total price for the lamp is $24.57.

you never say the total so we cant find the percentage used for petrol
