a pound of chocolate costs 8 dollars. Felipe buys p pounds. write an equation to represent the total cost c that felipe pays

alisha [4.7K]

Answer:

c=8p

Step-by-step explanation:

So, we know that 1 pound of chocolate will cost $8. Felipe is going to buy "p" pounds of chocolate, and "p" means "any number"; so Felipe is going to buy any number of pounds of chocolate.

The formula we would use to calculate this is cost of one pound of chocolate multiplied by number of pounds of chocolate. And the way we can form this algebraically is by writing c=8p.

The "c" stands for total cost and we don't have to put the multiply sign when using algebra, as long as the figures are touching.

A science museum makes gift bags for students using 168 magnets, 48 robot figurines, and 24 packs of freeze-dried ice cream. How

skelet666 [1.2K]

Answer:

7 magnets
2 robot figurines
1 pack of freeze-dried ice cream

Step-by-step explanation:

The greatest common factor of 24, 48, and 168 is 24, so 24 gift bags can be made. Each will have 1/24 of the number of gift items of each type that are available.

In each bag are ...

1/24 × 168 magnets = 7 magnets
1/24 × 48 robot figurines = 2 robot figurines
1/24 × 24 packs of ice cream = 1 pack of ice cream

_____

One way to find the greatest common factor (GCF) is to consider whether the smallest number divides all the numbers. If so (as here), then that is the GCF. If not, then consider the smallest difference between any pair of numbers, to see if it divides all of the numbers. If not, then test the smallest positive remainder from any of those divisions. Repeat until you have found a common divisor (which may be 1).

Kathleen is a high school student who has been investigating the possibility of mowing lawns for a summer job. She has a few fri

inna [77]

Answer:

She must pay $500 for the materials, and $14 per lawn, then:

We know that the total cost is (assuming that they work for 8 weeks, 6 days per week, and 3 times per day)

C = $500 + $14*(8*6*3) = $2,516.

The total revenue that she can make (with the same assumptions as before) is:

R = N*(8*6*3)

Where N is the amount she charges for each lawn that they mowed.

R = N*144

Now, we do not know how much she charges, so the value of N is unknown.

Now, the profit is equal to the difference between the revenue and the cost, this means that the profit is:

P = R - C = N*144 - ($2,516)

P(N) = N*144 - ($2,516)

If we have, for example, N = $20, the total profit will be:

P($20) = $20*144 - ($2,516) = $364

HELPPPPPPP MEEEEEEEEEEEEE

Evgesh-ka [11]

Number 1 is 2 because first you find out how many times 42 goes into 84 so you do 42x1, 42x2 and so on until you can't do anymore without going over 84 so 42x2 is 84 exactly so you put the two on top of the "house" above the 4 and put 84 under 84 then subtract 84-84=0 so you don't continue dividing and the number on top of the "house" is the answer

You play a gambling game with your friend in which you win 30% of the time and lose 70% of the time. When you lose, you lose $1.

Vadim26 [7]

Answer:

$ 2.33

Step-by-step explanation:

Fair game is when expected profit = 0

0.3(X) + 0.7(-1) = 0

0.3X = 0.7

X = 7/3

Approximately 2.33
