A lake currently has a depth of 30 meters. As sediment builds up in the lake, its depth decreases by 2% per year. This situation represents . The rate of growth or decay, r, is equal to . So the depth of the lake each year is times the depth in the previous year. It will take between years for the depth of the lake to reach 26.7 meters.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

$119.20

step-by-step explanation:

$372.50 - 60% off is $149. $149-20% off is $119.20
