What will the value of each card be when they have equal value?

Question

Tavon has a $50 gift card that loses $2 for each 30-day period it is not used. He has a $40 gift card that loses $1.50 for each 30-day period it is not used. What will be the value of each card be when they have equal value?

Answer 1

50-2m = 40 -1.5m

10 =.5m

m= 10/.5= 20 thirty day periods and they have the same value

50-2(20) = $10

40-1.5(20) = $10

Answer 2

Tavon has a $50 gift card that loses $2 for each 30-day period it is not used. He has a $40 gift card that loses $1.50 for each 30-day period it is not used. What will be the value of each card be when they have equal value?

A Step-by-step Explanation:

d= stands for the days not used

50-2d = 40-1.5d

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
