She pays 40% so 3292 times by 0.40 gives you 1,316.80 is what she pays.
Answer:
Step-by-step explanation:
Given is a Differential equation as
To bring it to linear form we can divide the full equation by x
This is of the form
y'+p(x) *y = q(x)
p(x) = 1/x
So find
Solution is
Use the initial value as y(e) =1
So solution is
Answer:
It would take 86.4 gallons of gas to go 1,836 miles.
Step-by-step explanation:
the situation can be explained by the equation 16x=340, where x is how many miles the car can go in one gallon. divide both sides by 16 to get that answer
x=340/16= 21.25
Now the other problem can be expressed by the equation 21.25y=1836, where y is the amount of gallons it would take to go 1,836 miles.
divide both sides by 21.25 to get the amount of gallons
y= 1836/ 21.25= 86.4.
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
7.5 is 30 percent of 25 because
25 divided by 10 is 2.5 times 3 is 7.5
