Respuesta :

there r 2 ways u can do this...

(1) find the unit rate...
     7500/6 = 1250 per day
     for 25 days.....1250 * 25 = 31250 tiles <==

or

(2) proportion..
     7500/6 = x / 25.....7500 tiles to 6 days = x tiles to 25 days
     cross multiply
     (6)(x) = (7500)(25)
     6x = 187500
     x = 187500/6
     x = 31250 <==

either way, u should get the same answer
C.31,250
6/7,500=25/x
187,500=6x
x=31,250
