a bat ate 1050 dragon flies on four consective nights. Each night she ate 25 more than the night before . How many did she eat each night ?

Let x  be the number for the first night.....so we have

(x) + (x + 25) + (x + 25 + 25) + (x + 25 + 25 + 25) = 1050    simplify

4x + 150 = 1050    subtract 150 from each side

4x = 900     divide both sides by 4

x = 225

So....the number for each night are

225..250..275..300
