2 x = 81 450 7 9 x = 81 450 7 1 x = 9050 7 x = 63 350
∴ Last year’s average value was $63 350. (c) Let the quoted price be $x. ∴x +
∴
1 x = 2457 20 21 x = 2457 20 1 x = 117 20 x = 2340
The gratuities =
1 of 2340 = $117. 20
(d) Let the value of the building be $x. 1 Value of the land = $ x − 2000 3 1 Total value of the property = $ x + x − 2000 3 1 ∴ x + x − 2000 = 184 000 3 4 x = 186 000 3 1 x = 46 500 3 x = 139 500 The value assigned to land is $(184 000 − 139 500) = $44 500. (e) Let the cost of power be $x.
3 Cost of heat = $ x + 22 4
