Answer:
$48.60
Step-by-step explanation:
4 7/5 can be expressed differently... but anyway..... this is how I got it.
5/6 kg ------> cost $7.50
1 kg ----> costs $7.50 ÷ 5/6 kg = $9
4 7/5 kg ------> costs $9 x (4 7/5) = $9 x (27/5) = $48.60
For Part A: the answer is 90 muffins total.
For Part B: the answer is 150 muffins total.
All you have to do is divide x (number of muffins the baker made) by 0.4 to get the total amount of muffins made.
Answer:
If f(1)=0 then 1 is a root and (x-1) is a factor of f(x). divide f(x) by (x-1). you now have a quadratic. Find its roots by methods you know.
actually this factors by grouping:
f(x)=x³+3x²-x-3
= x²(x+3)-1(x+3)
=(x+3)(x²-1)
=(x+3)(x-1)(x+1) // difference of squares
By zero product property roots are
-3, -1, 1
