Nicole wants to buy a charm bracelet. Summerfield Fine Jewelry charges $26 per charm, plus $19 for the bracelet. Flynn Jewelers, in contrast, charges $27 per charm and $11 for the bracelet. If Nicole wants to add a certain number of charms to her bracelet, the cost will be the same at either jewelry shop. How many charms would that be? What would the total cost of the bracelet be?

There are 8 number of charms

Total cost = $227

Step-by-step explanation:

Let

Number of charms = c

Summerfield Fine Jewelry charges $26 per charm, plus $19 for the bracelet.

26c + 19

Flynn Jewelers charges $27 per charm and $11 for the bracelet

27c + 11

How many charms would that be ?

Equate the cost at both jewelry shop

26c + 19 = 27c + 11

Collect like terms

26c - 27c = 11 - 19

-c = - 8

c = 8

There are 8 number of charms

What would the total cost of the bracelet be?

Using any of the jewelry shop cost

Flynn Jewelers cost

= 27c + 11

= 27(8) + 11

= 216 + 11

= 227

Total cost = $227

i just took the test, the correct answer is .. 31.5 in.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
