Please see the detailed answers below:
Step-by-step explanation:
Solution 1:
Sandwich = $9.25
Salad = $4.35
Tax = 7.5%
=> ($9.25 + $4.35) x 7.5 / 100 = 13.6 x 0.075 = $1.02
The amount of Tax on Veena's meal is $1.02
Solution 2:
Book read by Christian = (1/4) / (2/3) = (1/4) x (3/2) = 3/8
Christian will read 3/8 books per week.
Solution 3:
Sale Price = (100 - Discount Rate) x Cost Price
Let Y = Sale Price
By Putting the values in above equation:
Y = (100 - 45) x $650
Y = 0.55 x $650
Y = $357.5
Hence the Sale Price of the bicycle will be $357.5
Solution 4:
Percent error = [(Experimental Value - Accepted Value) / Accepted Value] x 100
Percent error = [(15.5 - 14.5) / 14.5] x 100
Percent error = [1 / 14.5] x 100
Percent error = 2.2%
Hence the percent error in Mark's estimate is 2.2%
