if the price of an item is $ 2.89 and sales tax is 8%, what is the total cost of the item including the sales tax?

Kipish [7]

To get the answer we have to find 8% of 2.89 and then add it to 2.89.
So,
8% of 2.89 its 0.08*2.89=0.23
0.23+2.89=3.12$ - its the answer

What is -3/4 + 3/8? Thanks.

AURORKA [14]

Answer:

$- \frac{3}{8}$

Step-by-step explanation:

First, we change both denominators to the LCM (lowest common multiple) which is 8.

$- \frac{3}{4} + \frac{3}{8} = - \frac{6}{8} + \frac{3}{8}$

Since the denominators are the same, we can add the numerators.

$\frac{ - 6 + 3}{8}$

$\frac{ - 3}{8}$

or it can be written as

$- \frac{3}{8}$

How much simple interest would you earn for 5 years at 7 with a beginning principal of $8 000.00

asambeis [7]

I=PRT
r=rate in percent
t=time in years
p=principal

convert percent to decimal
assuming you means at 7%
percent means parst out of 100
7%=7/100=0.07

so ow we have
p=8000
r=0.07
t=5
i=8000 times 0.07 times 5
I=40000 0.07
I=2800

interest=$2800

Y= 99<br> 9. Suppose a varies directly as b, and a = 7 when b = 2. Find b when a = 21.

kogti [31]

Answer:

6

Step-by-step explanation:

Given expression:

a varies directly as b;

a ∝ b

So;

a = kb where k is the constant of proportionality;

if a= 7 and b = 2;

7 = 2k

k = $\frac{7}{2}$

Now, find b when a = 21

21 = $\frac{7}{2}$ x b

b = 6
