Henrietta has $120 to buy a new bicycle. she finds the bike that she wants to buy on sale for 20% off the regular price of $150. if there is 6% sales tax, which of the following best describes the amount of money henrietta has with regards to buying the bike. a. henrietta has enough before the tax, but not enough after the tax. b. henrietta has enough money even after the tax. c. henrietta does not have enough money even before the tax. d. there is not enough information given.

Option A is correct, Henrietta has enough before the tax, but not enough after the tax.

Step-by-step explanation:

Henrietta has $120 to buy a new bicycle.

The price of bicycle = $150

After 20% discount the cost of bicycle = 150 - (150×0.20)

= 150 - 30 = $120

There is 6% sales tax = 120 + (6% of 120)

= 120 + (0.06 × 120) = 120 + 9.00 = $129.00

So the price of bicycle after adding sales tax is $129.00.

Henrietta has only &120.00, that is enough before the tax, but not enough after the tax.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

darn right!
