A plumbing supply company has fixed costs of $9,000 per month and average variable costs of $9.30 per unit manufactured. The com
nekit [7.7K]

Answer:

8710 units

Step-by-step explanation:

<em>Step 1: Write all the data</em>

Fixed cost: $9000

Average variable cost: 9.3 per unit

Total cost: 90,000

Total units: x

<em>Step 2: Find the total variable cost</em>

Average variable cost is per unit so it has to be multiplied by the number of units to find the total variable cost.

Total variable cost = average variable cost per unit x number of units

Total variable cost = 9.3x

<em>Step 3: Make the formula for finding x</em>

Total cost = total fixed cost + total variable cost

90,000 = 9000 + 9.3x

81000 = 9.3x

x = 8709.67

Rounded off to 8710 units

i have 17 coins. N of them are nickels and the rest are dimes. write an expression in two different ways for the amount of money
sergiy2304 [10]

Answer:

0.05N - 0.1N + 1.7 (in dollars

1.7 - 0.05N (in dollars)

Step-by-step explanation:

Given :

Total number of coins = 17

Number of nickels = N

Number of dimes = 17 - N

1 nickel = 5 cent = $0.05

1 dime = 10 cent = $0.1

The amount of money :

(Value of nickel * number of nickels) + (value of dime * number of dime)

(0.05 * N) + (0.1 * (17-N))

0.05N + 1.7 - 0.1N

0.05N - 0.1N + 1.7

-0.05N + 1.7 = 1.7 - 0.05N

SVEN [57.7K]

Answer:

Her account balance after 5 years is $8702.87

Step-by-step explanation:

1500 (1.05) = 1575 --> after one year

1575 + 1500 = 3075    

3075 (1.05) = 3228.75 --> after two years

3228.75 + 1500 = 4728.75

4728.75 (1.05) = 4965.1875 --> after three years

4965.1875 + 1500 = 6465.1875

6465.1875 (1.05) = 6788.44688 --> after four years

6788.44688 + 1500 = 8288.44688

8288.44688 (1.05) = 8702.86922 --> after five years = $8702.87

In 1998, Nkem Chukwu gave birth to the first set of surviving octuplets. The eight babies weighed from 11.3 ounces to 28.6 ounce
KiRa [710]

Answer:

The heaviest baby have to gain to reach a healthy level by 42 ounces.

Step-by-step explanation:

It is said that the 500-gram babies are going to have to make four times their weight [to reach a healthy level].

So, the healthy level of weight is (500 × 4) = 2000 gm i.e. 2 kg.

Now, 1 kg is equivalent to 35.274 ounces.

So, 2 kg will be equivalent to (35.274 × 2) = 70.548 ounces.

So, the heaviest baby with weight 28.6 ounces have to gain weight to reach a healthy level by (70.548 - 28.6) = 41.948 ounces ≈ 42 ounces. (Answer)
