75 divided by 15 equals 5 so each mouse cost $5.
nothing can be further simplify in this problem
So we start off by subtracting 137.3 from 180 getting 42.5. If you add the ratios up (3+4) you get 7 and 7 should equal 42.5. thus,
42.5/7= 85/14
(85/14)*3=18.2 or (255/14 to be exact)
(85/14)*4= 24.29 or (170/7 to be exact)
Ok i can help you solve this problem do you know the formula for quadratic equations
39.95 + 9.80 = 49.75
70.23 - 49.75 = 20.48
20.48 / 0.32 = 64
