Answer: 252,000 tsh
Explanation:
treat this as an percentage increase question, as you are adding 40% Of 180000 to the original cost to find the total price that it was sold at.
If this is a calculator questions, you can use
180000 x 1.4 = 252000
(This gives you 100% of the number + 40% of the number, as the selling price would be 140% of the cost , 140 / 100 would give you the multiplier)
If you cannot use a calculator, find 40% and add it to 180000
Divide by 10
10%= 18000
( x 4)
40% = 72000
180000+ 72000= 252000
