3.33 since we know 12 is for 40 we can set up an equation
Find 15% of 35:
0.15 * 35 = 5.25
Add it:
35 + 5.25 = 40.25
Now find 30% of this:
0.30 * 40.25 = 12.075
Add it:
40.25 + 12.075 = 52.325
So the price is approximately $52.33
Answer:
204
28=5 8=1
28+28=10 sheets
28×7=35 sheets
28x7=196
196+8=204
the plus 8 is for the extra page that is needed for 36
I am assuming the expression is (2x-3)(x+5) or (2x-3)(x-5). I will teach you how to solve for both as I am not sure which one you are asking for. There are 4 steps to multiplying.
1) Multiply the x times the second x
2) Multiply x times the second number
3) Multiply the number by the second x
4) Multiply the number by the second number.
(2x*x)+(2x*5)+(-3*x)+(-3*5)=(2
)+(10x)+(-3x)+(-15)=2
+7x-15
(2x*x)+(2x*-5)+(-3*x)+(-3*-5)=(2
)+(-10x)+(-3x)+(15)=2
-13x+15
Your answer is 2
+7x-15 or 2
-13x+15. Does that answer your question?
