Answer:
B. 2x + 4y
Step-by-step explanation:
If x = 4, and y = 7, let's substitute these values for x and y in the equations!
For A, the equation is 2xy. Substitute the values and you have 2(4)(7) which equals 56. This expression is incorrect since the expression doesn't equal 36.
For B, the equation is 2x + 4y. Substitute and you get the equation
2(4) + 4(7) → 8 + 28 = 36.
36 is your desired value, and you get that with the expression 2x + 4y.
If you were to get 30% backed off, lucky you !
You would then pay only the remaining 70%.
70% means 0.70
0.70 x $610 = <u>$427 </u>
First of all, remember that 100% is one whole thing.
Then.look at the problem, and see that 90 is three times 30.
-- 90 is 300% <em><u>of</u></em> an entire 30 .
-- To go from 30 to 90, you have to increase the 30 <em>by</em> 200% of itself.
