A shop recorded total sales of $2,000 on Monday. On Tuesday, its sales fell by 10%. On Wednesday, sales fell by another 20% comp
ared with Tuesday. From Wednesday to Thursday, sales increased by an amount equal to 25% of Monday’s total sales. What is the net change in total sales from Monday to Thursday?
20/(7-3) The difference of seven and three have to be in the parentheses because 20 is divided by the difference of the numbers not the numbers themselves.
