Question

the population of a city is expected to increased by 7.5%next year. If p represents the current population, which expression represents the expected population next year?

Answer 1

$1.075p$
 1.075p to represent “the expected population next year,” which may result from adding p, the current population, to 0.075p, the expected increase in population next year. The expression 1.075p relates the current population to the expected population next year using the expected percent increase.

Answer 2

P+(.075*p) because you add the whole population to the 7.5% that it increases
