A:7 dollars and 62 cents
B:149 dollars and 4 cents
C:136 dollars and 12 cents
D:151 dollars and 36 cents

Answer 1

Answer:

D

Step-by-step explanation:

100% = $143.74

1% = 100%/100 = 143.74/100 = $1.4374

5.3% = 1%×5.3 = 1.4374 × 5.3 = $7.61822

$143.74 + 5.3% = $143.74 + $7.61822

or

105.3% of $143.74 = 143.74 × 1.053 = 151.35822 ≈

≈ $151.36
