If the sales tax rate in New Mexico is 5.125% what is the sales tax in the total price for a roll toilet paper if it cost $3.50 what is the sales tax and total price for the coat if it cost $45.87?

1) The sales tax for the toilet paper is $0.17.

2) The price of the coat is $43.63 and the sales tax is $2.24.

Step-by-step explanation:

1) Let the cost of the toilet paper be 'a'

Sales tax = 5.125%

Total cost = $3.50

Total cost = price+ 5.125% of price

3.50 = a + (5.125 x a/100)

3.50 = (100a + 5.125a) /100

350 = 105.125a

a = 350/105.125

a = $3.33

Sales tax = 3.50 - 3.33

= $0.17

The sales tax for the toilet paper is $0.17.

2)let the price of the coat be 'a'

cost of the coat = $45.87

Cost = a + 5.125% a

45.87 = a + (5.125/100) a

45.87 = ( 100a + 5.125a) /100

4587 = 105.125a

a = 4587/105.125

a = $43.63

Sales tax = 45.87 - 43.63

= $2.24

The price of the coat is $43.63 and the sales tax is $2.24

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
