Step-by-step explanation:
Hello, I think I can help you with this
you can easily solve this by using a simple rule of three
Step one
If 1 mile is approximately 1.61 kilometers,it is
1 miles ⇔ 1.61 Kilometers
the, how many miles(x) are 89 km?
x ⇔ 89 kilometers
the relation is
Step two
solve for x( isolating x)

Have a good day
Your mistake is that week 3 is twice of week 2
week2=x+5, twice of that is 2(x+5)=2x+10, you did not distribute the 2 to the 5 and you got 2x+5, that is your mistake
x is first week
2nd week is y
3rd is z
5 more the 2nd week than 1st week
x+5=y
3rd week is double 2nd wee
z=2y
total is 431
x+y+z=431
sub
y=5+x and z=2y
x+5+x+2y=431
sub 5+x for y
x+5+x+2(5+x)=431
x+5+x+10+2x=431
4x+15=431
minus 15
4x=416
divide by 4
x=104
add 4
x+5=109
double
2*109=218
they sold
1st week: 104
2nd week: 109
3rd week: 218
I don’t know how to answer this question myself but you have to show some working out to this question!??
