Explanation;

Sales tax is computed as the product of the price times the tax rate in % divided by 100:

Sales tax = price × tax rate / 100

Here is each compute:

$299 × 4% = $299 × 4/100 = $11.96

$6,750 × 7% = $6,750 × 7/100 = $ 472.50

$76.50 × 5.2% = $76.50 × 5.2/100 =  $3.98

$18.32 × 3.9% = $18.32 × 3.9/100 = $0.71

$5.95 × 6.2% = $5.95 × 6.2/100 = $0.37

$13.89 × 4.3% = $13.89 × 4.3/100 = $0.60

$768.43 × 3.7% = $768.43 × 3.7/100 = $28.43

$6.49 × 5.8% = $6.49 × 5.8/100 = $0.38

$23.86 × 7.1% = $23.86 × 7.1/100 = $1.69

$12.98 × 3.9% = $0.51

450 is the final answer! : )

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
