60 +14*number of weeks

sister

120+10*number of weeks

let x be the number of weeks until they have the same amount of money

60+14x = 120+10x ; isolate like terms

14x -10x = 120-60

4x = 60; divide both sides by 4

x= 15 weeks

120+10*15 = 120+ 150 = $270 will be the amount they will have the same

This table shows some values of an exponential function. x у 01.25 1 2.50 25 3 10 What is the function?

Helen [10]

Answer:

$y= 1.25(2)^{x}$

Step-by-step explanation:

$y= 1.25(2)^{x}$

For x=0

$y= 1.25(2)^{0} = 1.25$

For x=1

$y= 1.25(2)^{1} = 1.25(2)=2.5$

For x=2

$y= 1.25(2)^{2} = 1.25(4)=5$

For x=3

$y= 1.25(2)^{3} = 1.25(8)=10$

Felicia bought a jackhammer priced at $8.48. The total price, including sales tax, was $9.73. What was the sales tax percentage?

lys-0071 [83]

Answer:

14.7%

Step-by-step explanation:

GIVEN: Felicia bought a jackhammer priced at $\$8.48$ . The total price, including sales tax, was $\$9.73$ .

TO FIND: What was the sales tax percentage.

SOLUTION:

Price of jackhammer $=\$8.48$

Total price including sales tax $=\$9.73$

Total sales tax on jackhammer $=9.73-8.48=\$1.25$

Total sales tax percentage $=\frac{1.25}{8.48}\times100=14.7\%$

Hence the total sales tax percentage on jackhammer is 14.7%
