Answer 1

First problem
5% discount on the flower vase, means 100-5=95% that now the vase costs 95% of the initial price
95% can be converted into decimals=0.95

95% of the initial price, or 0.95 of(times, *) the initial price
0.95*25 - the vase costs now

10% discount on the rug, means 100-0=90% that now the rug costs
90% of the initial price

90% can be converted into decimals=0.9

90% of the initial price, or 0.9 of(times, *) the initial price
0.9*48 - the rug costs now

0.95*25+0.9*48= %66.95 both items cost now
answer B $66.95

Second problem
P=P(initial)(1+rt)
P(initial)=500, rate=2%=0.02, t(time)=6 (years)
P= 500(1+0.02*6)= 560
B) $560
