Dear Amjelugo, we can subtract 4 from 50 to get $46. 4/6 hr= $8, 11/6 hr= $22, and 5/6 hr=$10. 10+22+8=$40 46-40=$6 $6=3/6 hr. Enrique walked Mrs. Camacho's dog and pick up her groceries for 3 hr.

Year 3: 1323 x .70= 926.1

Year 4: 926.1 x .70= 648.27

Year 5: 648.27 x .70=453.79

Solve for x (x/r)+(x/w)+(x/t)= 1

MissTica

x/r + x/w + x/t = 1

x (1/r + 1/w + 1/t) = 1

x = 1 / (1/r + 1/w + 1/t)

To make the solution a bit cleaner, multiply through the numerator and denominator by the LCM of each fraction's denominator, rwt :

x = 1 / (1/r + 1/w + 1/t) • rwt / rwt

x = rwt / (rwt/r + rwt/w + rwt/t)

x = rwt / (wt + rt + rw)
