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

Answer:

D) -1.8, -1 1/2 , 0.3 , 3/4 , 1

Step-by-step explanation:

Change all of the given terms to either fractions or decimals. Generally decimals are easier:

3/4 = 0.75

-1.8 = -1.8

1 = 1.0

-1 1/2 = -1.5

0.3 = 0.3

Order from least to greatest:

-1.8 , -1.5, 0.3 ,  0.75 , 1.0

or

-1.8, -1 1/2 , 0.3 , 3/4 , 1
