Answer:
f(-4) = 33
f(7) = -154
Step-by-step explanation:
In this question, you will solve the function by plugging in the given value.
Solve:
f(-4) = 7 - 2(-4) -3(-4)²
= 7 - 2(-4) - 48
= 7 + 8 - 48
= 7 - 40
f(-4) = 33
----------------------------------
f(7) = 7 - 2(7) -3(7)²
= 7 - 2(7) - 147
= 7 - 14 - 147
= 7 - 161
f(7) = -154

What percentage of his monthly budget does Doug put in savings?
O A. 13%
B. 6%
C. 11%
D. 16%
To get the percentage of his monthly budget does Doug put in savings, first we need to get the total savings
Total savings = 403+806+868+496+341+186
Total money = $3100
Amount spent on savings = $341
Percentage savings = amount spent on savings/Total money × 100%
Percentage savings = 341/3100 × 100
Percentage savings = 341/31
Percentage savings = 11%
Hence the percentage of the total money spent on savings is 11%
Subtract the totals and you get 223. Then divide 223/1538=14.5
