Question

Can anyone help me with my ques, please? I'm confused.
The local grocery store has videotapes on sale, $3.00 for 2 tapes. You have $20.
a) How many tapes can you buy?
b) If there is a 7% sales tax on the tapes, how many can you buy? (Explain your answers)

Answer 1

If 2 tapers are for $3
so i tape must be for 1.5

so what the maximum number of taper u can buy for $20

If u buy 13 tapes, it will cost $19.5

so thats the maximum number!

Answer 2

How did you bring the 19.5$ ?? I didn't understand!

Answer 3

20
--
1.5

13.33

so u cant have 0.33 disc.

therefore, 13 disks.

Answer 4

b)
1.5x.07=.105
thats the tax on each disc
now its 1.605 for each
now divide that into 20
20/1.605=12.46
which rounds down to 12
