Question

Denise builds two seawalls to keep rising water away from her house. The first is 8.75 meters long. The second is 37.5 percent longer than the first. How long is the second seawall?

Answer 1

okay so first u would do 37.5/100 * x/87.5
cross multiply get a result of 3.2815
add that to 8.75
end up with 12.0315
