Using a loyalty card at the local gas station store, Ella gets a free soda after buying 5 sodas at the regular price of 89¢. Same-sized sodas at the local fast food restaurant are 79¢ each. How do the two deals compare if Ella buys 6 sodas?HELP

The cost of buying 6 sodas at 79¢ each is greater than the cost of buying 5 sodas and getting 1 free

Step-by-step explanation:

Ella gets a free soda after buying 5 sodas at the regular price of 89¢

Total cost of 6 sodas( 5 + 1 free)

= 89¢ × 5

= 445¢

Same-sized sodas at the local fast food restaurant are 79¢ each.

Total cost of 6 sodas = 79¢ × 6

= 474¢

The cost of buying 6 sodas at 79¢ each is greater than the cost of buying 5 sodas and getting 1 free

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
