Answer:
20) 8 years
21) Tori could paint the room alone for 3 hours, Sydney could paint the room alone for 5 hours.
Step-by-step explanation:
A = P ( 1 + r/n ) ^ nt.
8000 = 5000 ( 1 + 6%/4) ^ 4t
8000 = 5000 ( 1 + 0.06/4) ^4t
8000 = 5000 ( 1 + 0.015 ) ^ 4t
8000 = 5000 ( 1.015 ) ^ 4t
8000 / 5000 = ( 4.06 / 4 ) ^ 4t
8/5 = ( 203/200 ) ^ 4t
b = aᶜ ⇔ logₐb = c

Step-by-step explanation:
The question is incomplete:
Tavon has a gift card for $115 that loses $2.50 for each 30-day period it is not used. He has another gift card for $95 that loses $2 for each 30-day period it is not used.
Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal.
Answer:
115-2.5x=95-2x
The value of the gift cards will be equal after 40 30-day periods.
Step-by-step explanation:
From the information given, you can write the following equation:
115-2.5x=95-2x, where x is the number of 30-day periods the gift card is not used.
Now, you can solve for x:
115-95=-2x+2.5x
20=0.5x
x=20/0.5
x=40
According to this, the answer is that the value of the gift cards will be equal after 40 30-day periods.
