Answer 1

d. Solution The amount on the initial Bill = $280 The amount on the final bell after agrement 25% lower than Onitial Bill |- 25 * $280 loo = (1 -0.25) X 280 0.75X260 So the -$210 amount on the final Bill after agreement $210 and the beas at the place $280 to give only $210 because of agreement repairing technician agreed sto take only $ 210 concession af $ of and gave $70.

(2. sluhom floor space that store hob = 1200 square feet Exponding so% of the 50% of the floor Space - 1200 x to grocery store hob = 12450 = 600 square feet Expanding 25% of the floor space 12048x 25 Tony = 12 X 25 = 300 square feet So After these two expansions, grocery Bhore have flor space = (1203 + Goo+309 the 2100 square feel so, After these two expension, the grocery store have 2000 square feet of floor space
