**Math percentage**

I don't really understand percentages grade 6 math. 1.60% discount on a 7$ item so items price is 40% of original so 0.4 x 7= 2.8$? 2. A population of 1500 people increases 15% each year how would this question be done? 1500 x .15=225 so the next years population would be 225...
