6.89(1.21) = 8.3369 rounds to 8.34 <==

or u could also do it this way...
6.89 + 0.21(6.89) = 6.89 + 1.4469 = 8.3369 rounds to 8.34 <==

Answer:

Option C is correct.

Step-by-step explanation:

Base Price of a roast chicken = $ 6.89

Increase in Price = 21 %

So,

New Price = Base price + Increased amount

                 =  6.89 + 21 % of 6.89

                 =  6.89+\frac{21}{100}\times6.89

                 =  6.89+\frac{144.69}{100}

                 =  6.89 + 1.4469

                 =  8.3369

                 =  $ 8.34 (to nearest cent)

Therefore, Option C is correct.

"Increasing" and "decreasing" are references to what the y-values do when the x-values increase.  

Attached is a copy of all four tables, marked with whether the y-values increased or decreased on each step (and it also shows how much that increase or decrease was.

The only table that does this is the top right table in the attachment, which is your second table.

a 5 inch tall bamboo shoot doubles in height every 3 days. if the equation, y=ab^x where x is the number of doubling periods, re
Lemur [1.5K]
X-doubling periods
Y-height of bamboo
Y=ab^x

1) make a table of values
X Y
1 5
2 10
3 20

2) write equations and substitute
5=ab^1 —> a=5/b^1 —> a=5/b
10=ab^2

Substitute into second equation

10=(5/b)*b^2
10=5b^2/b
10=5b
b=2

Substitute back in

b=2
10=a*2^2
10=4a
a=5/2

End equation:
Y=5/2*2^x
