The total price would be $3.56 times however many you bought, so the correct equation would be x = 3.56k.
Answer: you will have 56
Step-by-step explanation:
Answer: (B) 3 times as fast
<u>Step-by-step explanation:</u>
rate of change is the "slope" between the given interval.
f(x) = 125(.9)ˣ
f(1) = 125(.9)¹
= 112.5
f(5) = 125(.9)⁵
= 73.8

********************
f(11) = 125(.9)¹¹
= 39.2
f(15) = 125(.9)¹⁵
= 25.7

********************
The rate of change from years 1 to 5 is approximately 3 times the rate of change from years 11 to 15.
Let x be the price of each pen and y be the price of each pencil. From the given, the equations that are described are,
6x + 8y = 8.50
4x + 4y = 5
Solving for x and y simultaneously gives an answer of x = 0.75 and y = 0.5.
Thus, each pen costs $0.75 and each pencil costs $0.50.
