Answer:
Step-by-step explanation:
let number of dimes=x
nickels=x+3
pennies=4x
10 (x)+5(x+3)+4x=110
10 x +5x+15+4x=110
19x=110-15=95
x=95/19=5
dimes=5
nickels=5+3=8
pennies=4*5=20

After 2.80 years the price drops to 300 $
Step-by-step explanation:
Ryan bought a new computer for $2,100.
Price of computer = 2100 $
The value of the computer decreases by 50% each year.
Let p(n) be the price of computer after n years.
Now we need to find n when price is 300 $.
0.50ⁿ x 2100 = 300
0.50ⁿ = 0.143
n log (0.5) = log 0.143
n x -0.301 = -0.845
n = 2.80
After 2.80 years the price drops to 300 $
