41. tavon has a $50 gift card that loses $2 for each
30-day period it is not used. he has a $40 card
that loses $1.50 for each 30-day period it is
not used.
a. write and solve an equation for the number
of 30-day periods until the value of the gift
cards will be equal.
b. what will the value of each card be when
they have equal value?

Step-by-step explanation:

d=days not used

50-2d  =  40-1.5d

subract 40 each side

10-2d =1.5d

10= 0.5d

20=d

After 20 days the value of the gift  cards will be equal.

20*2=40      50-40=10 ($10)

20*1.5=30     40-30=10 ($10)

each card will have a value of $10  after 20 days,when both cards have equal value

where is the graph? need more info

it is impossible.
