Answer:
Price in Japan= 17.81
Price in Switzerland = 13.58
Step-by-step explanation:
First set up system of equations
80.59 = 3j +2s
76.36 = 2j + 3s
Make it to where you can eliminate one variable
161.18 = 6j +4 s
-229.08 = -6j - 9s
Reset the problem
-67.9 = -5s
s=13.58
Re plug them in to the original equation to get j = 17.81
We can always do a prime factoring of it, and check
50 = 2*5*5
2*5²
a perfect square, so-called, is the resulting number of a squared value, well 50 is not the result of anything squared, is the result of 3 factors, in this case 2,5 and 5.
a perfect square will be something like say 64, or 144, because
64 = 8*8
8²
144 = 12*12
12²
From 145 pounds to 132 pounds
145 - 132 = 13
13 pounds
Check:-
132 + 13 = 145
Correct!
13 pounds
