Question

A store sells small notebooks for $8 and large notebooks for $10. If you buy 6 notebooks and spend $56, how many of each size notebook did you buy?

my answer: 7 small notebooks and 5 large notebooks
is this right?

Answer 1

Let x be the number of notebooks bought for $10. Let y = number of notebooks for $8

Then x + y = 6 and 10x + 8 y = 56

Now solve (:

Answer 2

If you only bought 6 notebooks, how do you get 7 and 5? You need to read the problems carefully.

x = 6-y

10x + 8y = 56

Substitute 6-y for x and solve.

Answer 3

Y=2 x=4

Answer 4

1-1 THEN ADD 3 TO 6 THEN WHAT YOU WILL HAVE.
