Let x be the number of hours worked. 

800 + 16x = 720 + 21x
800 - 720 = 21x - 16x
80 = 5x
x = 16
∴ A job that would cost the same would take 16 hours.

Now to double check...
800 + 16 x 16= 1056
720 + 16 x 21= 1056

The answers are correct.

8_murik_8 [283]

Answer:

The prices at which manager predict that at least 55 hats will be sold would be would be of $38

Step-by-step explanation:

According to the given data we the following:

Number of hats sold at $18=115

The manager predicts at 3 less will sold for every rise in 1 $ for at least 55 hats.

Therefore, reduction in number=115 hats-55 hats=60

So, increase in price=reduction in number/number of hats manager predicts that  will be sold for every $1 increase in price

increase in price=60/3=$20

Therefore, prices at which manager predict that at least 55 hats will be sold would be=$18+$20=$38

The prices at which manager predict that at least 55 hats will be sold would be would be of $38

Translate the given phrase into an algebraic expression and simplify if possible: the product of -13 and the difference of c
Musya8 [376]

Answer:  -13c+13d

Step-by-step explanation:

For this exercise it is important to remember the following:

1. By definition, the "Product" is the result of a multiplication.

2. The "Difference" is defined as the result of a subtraction.

3. The Distributive property states that:

a(b+c)=ab+ac\\\\a(b-c)=ab-ac

Keeping the above on mind, you know that:

"The difference of c and d" can be represented with the following expression:

c-d

Therefore, "The product of -13 and the difference of c and d" can be represented with this expression:

-13(c-d)

Finally, you must apply the Distributive property in order to simplify the expression. You get:

=-13c+13d

Here are some prices customers paid for different items at a farmer’s market. Find the cost for 1 pound of each item.
posledela

Answer:

  • 1 pounds of apples = \1·25
  • 1 pounds of cheese = \7
  • 1 pounds of coffee beans = \5·5
  • 1 pounds of fudge = \9
  • 1 pounds of pumpkin = \0·88

Step-by-step explanation:

Unit Rate is the ratio between two different quantities with different units

The ratio of cost per items is

=  \frac{dollars}{pounds}

4 pounds of apples  = \5

4 pounds = \5

Divided 4 both the side

1 pounds of apples = \1·25

\frac{1}{2} pounds of cheese = \3·50

\frac{1}{2} pounds = \3·50

Divided \frac{1}{2} both the side

1 pounds of cheese = \7

\frac{3}{2} pounds of coffe beans = \8·25

\frac{3}{2} pounds = \8·25

Divided \frac{3}{2} both the side

1 pounds of coffee beans = \5·5

\frac{3}{4} pounds of fudge = \6·75

\frac{3}{4} pounds = \6·75

Divided \frac{3}{4} both the side

1 pounds of fudge = \9

\frac{25}{4} pounds of pumpkin is = \5·50

\frac{25}{4} pounds = \5·50

Divided \frac{25}{4} both the side

1 pounds of pumpkin = \0·88
