Answer:
Step-by-step explanation:
You would never buy a 10-pack, because two 5-packs cost less.
To buy 3 bars you need a single bar and a pair of single bars for £0.82 + £0.82+ £0.41 = £2.05
To buy 30 bars you need 3 pairs of 5-bar packs = 3×£5.75 = £17.25
To buy the remaining 5 bars you need one 5-bar pack = £3
cost = £2.05 + £17.25 + £3 = £22.30
Answer:
Markup amount: $54
New price with markup: $204
Step-by-step explanation:
36% markup to $150
We can find the amount of markup by finding 36% of 150.
36% of $150
Write 36% as a decimal and multiply it by the price
0.36(150) = $54
The amount of markup (36%) is equal to $54
When this is added to the original price, the new price is $150 + $54 = $204

"Finding Derivatives Implicity In Exercise,Find dy/dx implicity . 
"
Answer : 
Step-by-step explanation:
From the expression " y is define as an implicit function of x, hence we differentiate each term of the equation with respect to x.
we arrive at
for the expression 
we differentiate using the product rule, also since y^2 is a function of y which itself is a function of x, we have
.
if we make dy/dx subject of formula we arrive at
Answer: y=2x+8
Step-by-step explanation:
(2,12)=(x1,y1)
(-7,-6)=(x2,y2)
(y2-y1)/(x2-x1)=(-6-12)/(-7-2)=-18/-9=2=m
y=mx+b
y=2x+b
insert (2,12) to y=2x+b
12=2*2+b
12=4+b
8=b
y=2x+8
