Let the price of 1 litre of milk be x$
Let the price of 1 loaf of bread be y$
According to the problem
333x + 555y =11
444x+444y=10
On subtracting the two,
We get
(333x+555y=11) * 444
(444x+444y= 10) * 333
(-) (-) (-)
147852x + 246420y =4884
147852x + 147852y = 3330
(-) (-) (-)
------------------------------
98568y = 1554
y = 1554/98568
= 0.0157$
=0.02$
Price of 1 loaf of bread= 2 cents
On putting the value of y
333x + 555*0.0157 = 11333x + 8.7135 = 11333x = 2.2865x = 2.2865/333x = 0.00068$ = 0.01$
Price of 1 litre of milk = 1 cent
1.5
Answer:
67%
Step-by-step explanation:
First of all, we must find the decrease;
39 - 13
=26
Then we can find the percentage decrease
26/13 ×100 =66.666..which can be written as 67.
The 25th arithmetic term will be -67
That would be the symmetric property of equality
-5/16 is equal to -0.3125 in decimal form
