There are 75.29 quarters and 79.29 dimes in the jar.

Given,

In his change jar, Thomas collects dimes and quarters.

So if he has 4 more dimes than quarters, and the total amount of money in the jar is $26.30

Thus,

Let, x be the number of dimes.

And y be the number of quarters.

If Thomas has 4 more dimes than quarters,

y = x + 7

On the other hand, the total amount of money in the jar is $26.30.

0.24x + 0.10y = 26.30

Substitute the value of y in the given equation 2

0.24x + 0.10y = 26.30

0.24x + 0.10 (x+7) = 26.30

0.24x + 0.10x + 0.7 = 26.30

0.34x = 26.30 - 0.7

0.34x = 25.6

x = 25.6 / 0.34

x = 75.29

Substitute the value of x in the given equation 1

y = x + 4

y = 75.29 + 4

y = 79.29

Hence, there are 75.29 quarters and 79.29 dimes in the jar.

love history [14]

Answer:

The correct answer is 31 customers per day.

Explanation:

Consider the current capacity requirement as = x

Management wants to have a capacity cushion = 8%.

So the utilization is required = 100% - 8% = 92%

A process of currently services an average of 43 customers per day and utilization is 90%.

Expected Demand=70%= 70 ÷ 100 = 0.70

Current utilization = 90% = 0.90

Let Capacity requirement = X

Capacity requirement ÷ required utilization  = Expected Demand rate × current service rate ÷ current utilization rate

X ÷ 0.92  = 0.70 × 43 ÷ 0.90

X = 0.70 × 43 ÷ 0.90 × 0.92

= 30.76  or 31

Needed capacity requirement is 31 customer per day.

Brrunno [24]

Answer:

The cost of equipment = $127,650

Explanation:

<em>According to International Accounting Standards (IAS) 16, property plants and equipment, the cost of land includes all of the cost necessary to bring and make it ready for the intended use.  </em>

<em>These costs include purchase cost, fees and commission associated with the purchase transaction. </em>

Here in this question the installation charges, sales taxes and the cost of concrete slab all fall within the definition of IAS 16

The quotation 4/10, n/30 implies that if payment is made within =10 days, Crane would get 4% off the initial purchase price.

Since the payment was made within the discounted period, the net purchase price would be

Purchase price = 120,000 - (4%× 120,000)= 115,200

The cost of equipment = 115,200 +4,750 + 2,100 + 5600= 127650

The cost of equipment = $127,650
