HELP. ASAP. EASY MUTIPLE CHOICE QUESTIONS.<br>​
Alina [70]

Answer:

C 44.59

Step-by-step explanation:

The first two shirts are full price

2*49.96 = 99.92

The third shirt is 50% off.  That means it is 50% of the original price

.5*49.96 = 24.98

The total cost before tax is

99.92+24.98 =124.90

tax = cost * tax rate

tax = 124.90*.071

tax=8.87

Add this to the cost

final cost = 124.90+8.87

                =133.77

We want to find the mean cost (average cost)

Take the total cost and divide by the number of shirts

133.77/3 =44.59

Mark has $100,000 to invest. His financial consultant advises him to diversify his investment in three types of bonds: short-ter
galina1969 [7]

Answer:

Short-Term investment: 5000$

Intermediate-Term investment: 65000$

Long-Term investment: 30000$

Step-by-step explanation:

To construct our first equation lets define sort-term bond investment as x, long-term investment as y.

So the equation is:

x*0,04+(100000-x-y)*0,05+y*0,06=5250

From the equation it is found that:

y=25000+x

Instead of y, if we put 25000+x the equation will be as following:

x*0,04+75000*0,05+(25000+x)*0,06=5250

From the equation it is found that:

x=5000

Short-Term investment is 5000$

x+25000=y

Long-Term investment is 30000$

Rest of the money is Intermediate-Term investment 65000$

The explicit rule for the arithmetic sequence is a(n) = 7n + 8 if the arithmetic series is 15, 22, 29,...

<h3>What is a sequence?</h3>

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have:

In the first week, only 15 shirts were sold. In the next week, 22 shirts were sold and in the third week, 29 shirts were sold.

15, 22, 29,...

The first term a = 15

The common difference d = 22 - 15 = 7

a(n) = 15 + (n - 1)7

a(n) = 7n + 8

Thus, the explicit rule for the arithmetic sequence is a(n) = 7n + 8 if the arithmetic series is 15, 22, 29,...
