Mr. Hughes gave 5/14
kow [346]

Answer:

His savings were of $4,200.

Step-by-step explanation:

Mr. Hughes gave 5/14 of his savings to his son, 2/3 of the remainder to his daughter, and the rest to his wife:

This means that the son and daughter amount is:

\frac{5}{14} + \frac{2}{3}(\frac{9}{14})

As \frac{9}{14} is the remained that his son did not get. So

\frac{5}{14} + \frac{2}{3}(\frac{9}{14}) = \frac{15}{42} + \frac{18}{42} = \frac{33}{42}

Fraction his wife got:

1 - \frac{33}{42} = \frac{42}{42} - \frac{33}{42} = \frac{9}{42}

If his wife got $900, what were his savings?

Total savings are x, wife got \frac{9}{42} of x. So

\frac{9x}{42} = 900

9x = 900*42

x = \frac{900*42}{9}

x = 100*42

x = 4200

His savings were of $4,200.

BlackZzzverrR [31]

Answer: Sales tax is $4.80 and the total cost is $64.80

Step-by-step explanation: Take the difference in the total before and after tax and divide by the price before tax.

To get $4.80, find the sales tax of $60.00 of 8%

We can use this formula: (selling price x sales tax rate)

The sales tax is: $4.80

To find the total cost, add 60.00 by the sales tax. ($4.80)

60.00 + 4.80 = $64.80

Therefore, these are your answers: $4.80 and $64.80
