The cost, c, of a ham sandwich at a deli varies directly with the number of sandwiches, n. If c = $54 when n is 9, what is the c
2 answers:
Answer:
Option A is correct that is $18
Step-by-step explanation:
We have been given an information that is
c=$54 when n =9
when 9 gives 54
Then 1 gives 54/9
cost for one sandwich that is when n=1 then
We need to find the cost for 3 sandwiches that is when n =3 then
when cost for one sandwich is 54/9 then cost for 3 sandwiches is
Therefore, Option A is correct tha is $18.

<h3>To find the product of 42.12 and 10^3, move the decimal point in 42.12 3 places to the right because 10^3 has 3 zeros</h3>
<em><u>Solution:</u></em>
Given that,
Which means,
Here, the exponent of 10 is positive ( which is 3)
When the exponent is positive, we have to move the decimal point to right
When you multiply a number by a power of 10, ( 10!, 10^2, and so on ) move the decimal point of the number to the right the same number of places as the number of zeros in the power of 10
Here, exponent is 3 , therefore move the decimal point right 3 places in 42.12
Therefore,
