1. 12%=.12, 1/4=.25, 3/10=.3   These are just ratios that need to be multiplied by your total.
A.
     roof cost  = .12(200000)= 24000
     beds cost = .25(200000) = 50000
     refit cost  = .3(200000) = 60000
     bank deposit = total grant - total expenditure = 200000-134000 = 66000

B.
     fraction deposited = bank deposit / total grant = 66000 / 200000 = .33 or 33%

2.
     cost a = (15-1)700 = 9800
     cost b = 15(600) + .01(15)600 = 9000 + 90 = 9090
     Therefore cost b is much cheaper.

     savings = cost a - cost b = 710
