Anna and jason have summer jobs stuffing envelopes for two different companies. anna earns $14 for every 400 envelopes she finishes. jason earns $9 for every 300 envelopes he finishes. suppose jason has savings of $100 at the beginning of the summer and he saves all his earnings from his summer job. how many envelopes would anna and jason have to stuff for their savings to be equal? what are their savings?

ratio is 2 : 9

the answer is three

13.5 : 3

c

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
