The rate of change is 2om per hour
Decreasing by $52 every year, we need to subtract 52 for each year.
350 is the original price.
52x is the amount decreased by how many years
350 - 52(3) = ?
350-156 = 194
Answer: Matt should sell his iPod for $194 in 3 years
Answer:
x = rd/c
Step-by-step explanation:
xc = rd
xc/c = rd/c
x = rd/c
10t = b - 4
12b+8t = $348
This is a system of equations. I’ll be solving through substitution.
In the first equation. solving for b (the easier variable to isolate) gives you:
b = 10t + 4
Substitute this into the second equation:
12(10t+4) +8t = 348
120t+48+8t = 348
128t = 300
t = 2.34375 —> round it to the nearest cent to get 2.34 dollars
b = 10t+4
b = 10(2.34)+4
b = 27.4 dollars
