Answer:
Step-by-step explanation:
1) Number of white chocolate bars = x
Number of dark chocolate bars = y
Total bars = 15
x + y = 15 --------------(I)
Total cost = Php. 340
20x + 25y = 340 ----------------(II)
2) We can use elimination method to solve this equations.
Multiply equation (I) by (-20) and then add the equations.
(I)* (-20) -20x -20y = - 300
(II) <u>20x + 25y = 340 </u> {Now add and x will be eliminated}
5y = 40
y = 40/5
y = 8
Substitute y = 8 in equation (I)
x + 8 = 15
x = 15 - 8
x = 7
3) Number of dark chocolate bars = 8
Hey there! I'm happy to help!
If something is 11 less, we are subtracting 11.
-11
We have 11 less than seven times a number x.
7x-11
The word is means equals.
7x-11=-4
Now we need to isolate the x. We add 11 to both sides.
7x=7
We divide both sides by 7.
x=1.
Have a wonderful day! :D
