Answer:

Step-by-step explanation:

case 1

cost of 20oz bottle of soda = $1.20

dividing both side by 20

cost of 20/20 oz bottle of soda = $1.20/20

cost of 1oz bottle of soda = $0.06

__________________________________________

Case 2

cost of 12oz bottle of soda = $0.85

dividing both side by 12

cost of 20/20 oz bottle of soda = $0.85/12

cost of 1oz bottle of soda = $0.07

Based on above calculation, we can see that first deal 20oz bottle of soda at costs $1.20 is better deal as per unit cost is $0.06 which is less than 12 oz can of soda costs $0.85 which is equivalent to  $0.07 per unit cost

6x-5y = 15<br><br> x=y+3<br><br> x=<br><br> y=
Zina [86]

Answer:  x = 0  y = –3

Step-by-step explanation:

We can solve this system by substitution.

use the second equation as a value for x.

Then substitute that value  in place of x in the first equation and solve for y.

6x - 5y = 15 becomes

6(y + 3) - 5y = 15  Distribute 6 × parentheses

6y + 18 - 5y = 15 combine like terms

6y -5y + 18 = 15

y + 18 = 15   Subtract 18 from both sides.

y =15 -18

y = –3

Use this value for y in either equation to solve for x

6x - 5(-3) = 15

6x + 15 = 15    Subtract 15 from both sides, divide by 6 (seems silly!)

x = 0

OR in he second equation,

x = -3 + 3  

Again, x = 0

Tpy6a [65]

Answer:

Annual deposit= $3,474.39

Explanation:

Giving the following information:

You want to have $60,000 in your savings account 12 years from now, and you’re prepared to make equal annual deposits into the account at the end of each year. The account pays 6.4 percent interest.

FV= {A*[(1+i)^n-1]}/i

A= annual deposit

Isolating A:

A= (FV*i)/{[(1+i)^n]-1}

A= (60,000*0.064)/[(1.064^12)-1]= $3,474.39
