9. Brian has been saving money to buy a 55-in. Samsung LED television. He has saved $1680 so far, but this is only 70% of the total cost of the television. What is the total cost? ___________________________________________________
10. A new coat costs $71.25. If the sales tax rate is 5%, what is the total bill? _________
8. To find the percentage, divide the number of panthers living in Everglades National Park (11) by the total number of panthers living in the wild in Florida (87) and multiply by 100.
(11/87) * 100 = 12.6%
The percentage, rounded to the nearest tenth, is 12.6%.
9. To find the total cost of the television, divide the amount saved ($1680) by the percentage saved (70%) and multiply by 100.
($1680 / 70) * 100 = $2400
The total cost of the television is $2400.
10. To find the total bill, multiply the cost of the coat ($71.25) by the sales tax rate (5%) and add the result to the cost of the coat.
($71.25 * 0.05) + $71.25 = $74.81
The total bill, including sales tax, is $74.81.
