Jess observed that 60% of the people at a mall on a particular day shopped for clothes. if 2500 people at the mall did not shop for clothes that day, the number of people who shopped for clothes that day was (only put numeric values, no other symbols)

If 60% is shopping, then 40% is not shopping (100% - 60%=40%). You can use a cross-multiplication, or the rule of three for the equivalences, I mean:
2500/40% = x/60% so you solve for x and get x = 60%*2500/40% = 3750 people who shopped that day.

All points to the left of zero on a horizontal number line are negative. a number line is a picture of a graduated straight line that serves as abstraction for real numbers. this number line can be extended to the left to represent numbers which are smaller than 0. such numbers are called negative numbersmark me brainliest
