If a customer uses 80 MB, the monthly cost will be $19.00. If the customer uses MB, the monthly cost will be $. Find a linear eq

CaHeK987 [17]

Answer:

$c = 4.211\cdot n$

Step-by-step explanation:

The linear equation has the following form:

$c = \frac{\Delta C}{\Delta n} \cdot n$

Where:

$n$ - Number of MBs of the data plan.

$c$ - Monthly cost of the data plan.

The slope of the function is:

$\frac{\Delta C}{\Delta n} = \frac{c}{n}$

$\frac{\Delta C}{\Delta n} = \frac{80\,MB}{19\,USD}$

$\frac{\Delta C}{\Delta n} = 4.211\,\frac{MB}{USD}$

The equation is:

$c = 4.211\cdot n$

Answer:

Hello,

I have reply too quick in comments (sorry)

Step-by-step explanation:

$\left\{\begin{array}{ccc}log_x (27)+log_y (4)=5\\log_x (27)-log_y (4)=1\\\end{array}\right.\\\\\\\left\{\begin{array}{ccc}2*log_x (27)=6\\2*log_y (4)=4\\\end{array}\right.\\\\\\\left\{\begin{array}{ccc}log_x (27)=3\\log_y (4)=2\\\end{array}\right.\\\\\\\left\{\begin{array}{ccc}x^{log_x (27)}=x^3\\y^{log_y (4)}=y^2\\\end{array}\right.\\\\\\\left\{\begin{array}{ccc}27=x^3\\4=y^2\\\end{array}\right.\\\\\\\left\{\begin{array}{ccc}x=3\\y=2\\\end{array}\right.\\\\$

one bag of pretzels cost three dollars. five bags of pretzels cost $10.which has the lower unit price

Karo-lina-s [1.5K]

5 bags is cheaper because one bag is $3 and 5 bags for ten so to find the unit price the amount (10/ ) the amount of bags (5) so therefore 10/5= $2 which is smaller than the price of an individual bag
