Let s = #small notebooks
Let L = #large notebooks
We Can set up two equations from the info given.
s + L = 6 bought 6 notebooks total
8s + 10L = 56 spent $56
Solve equation 1 for one variable.
L = 6-s
Plug 6-s in equation 2 in place of L
and solve for s
8s + 10(6-s) = 56
8s + 60 - 10s = 56
-2s + 60 = 56
-2s = -4
s = (-4)/(-2)
s = 2
We know s+L = 6 and s=2
2+L = 6
L = 4
4 large notebooks and 2 small notebooks
were purchased
Draw a x on the square to make 4 triangles. triangles have a total of 12 sides.
Answer: $30.40
Step-by-step explanation: If you know that the original price is $38 and it was marked down by 20%, you could multiply the original price by ".80". This represents 80% of the original cost, since it was marked down by 20%. By multiplying $38 by .80, you end up with $30.40.
