How do you go about solving this problem?

Question

If the total cost of x apples is b cents, what is the general formula of the cost, in cents, of y apples?

I need to know how you reached the solution. TIA!!

Answer 1

cost of x apples=b cents
cost of 1 apple=b/x
cost of y apples(direct ratio)
SO Y(B/X)CENTS

Answer 2

Think this way: if cost of 5 apples was $4, what would be cost of one apple. Ans 4/5 dollar ( 80 cents) If cost of x apples is b cents then cost of one apple is b/x. mult by number of apples bought y

Cost = y(b/x)
Hope this helps

Answer 3

cost of x apples is b cents
cost 1 apple is b/x cents
cost y apples=y*b/x cents

Answer 4

cost=(b*y)/x
the ratio of x apples to b cent will be same as y apples to cost of y apples in cents
so,x/b=y/cost of y apples,
cross multiplication will give you cost=(b*y)/x

Answer 5

b=x times (cost of each apple)
so
divide by x
b/x=(cost of each apple)
therefore
cost of y apples =y times (cost of each apple)
is
cost of y apples = y times (b/x)
=
yb/x

Answer 6

cost of x apples=b
cost of 1 apple=b/x
cost of y apples=b/x *y

Answer 7

y * b = x

y times b = x

(i think that is right)
