Answer:

1. $14.70

2. $1.60

3. $135.30

4. $8.25

Explanation:

1. Convert percentage to decimal:

30% = 30/100 = 0.3

So 30% of $49 = 0.3 x 49 = 14.7

Therefore, a discount of 30% = a discount of $14.70

2. Convert percentage to decimal:

20% = 20/100 = 0.2

So 20% of $8 = 0.2 x 8 = 1.6

Therefore, the 20% tip = $1.60

3. Convert percentage to decimal:

20% = 20/100 = 0.2

So 20% of $112.75 = 0.2 x 112.75 = 22.55

Therefore, total cost with the tip = 112.75 + 22.55 = $135.3

4. If a discount of 45% is applied, the new cost of the shirt will be 55% of its original price (as 100% - 45% = 55%)

Convert percentage to decimal:

55% = 55/100 = 0.55

So 55% of $15 = 0.55 x 15 = 8.25
