Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Cost of large candle (a) = 25 each
Cost of small candles (y) = 10 each
Amount needed = $600
Number of each that must be sold to raise needed amount:
25a + 10y = 600.
Here a = number of large candles that must be sold at the price
y = number of small candles that must be sold at the price
Summing the revenue both should result in the required amount.
F(x) = 3x - 2
f(8) = 3(8) - 2
f(8) = 24 - 2
f(8) = 22
f(-5) = 3(-5) - 2
f(-5) = -15 - 2
f(-5) = -17
f(8) - f(-5) = 22 - (-17)
f(8) - f(-5) = 39
Hope this helped! Good luck! :)
