The miller family visited mama's kitchen and ordered 4 hamburgers and 3 medium fries and paid $13.44. james ordered a medium drink, a hamburger, and 2 medium fries and paid $5.81. steven ordered 2 hamburgers, medium fries, and a medium drink for $7.35. how much did each item cost?

Hamburger costs $2.58

Fries costs $1.04

Drink costs $1.15

Step-by-step explanation:

Let hamburgers cost = h

Let fries cost = f

Let drinks cost = d

The Miller family visited Mama's Kitchen and ordered 4 hamburgers and 3 medium fries and paid $13.44.

    ....(1)

James ordered a medium drink, a hamburger, and 2 medium fries and paid $5.81.

   ....(2)

Steven ordered 2 hamburgers, medium fries, and a medium drink for $7.35.

   ....(3)

Subtracting (2) from (3) to eliminate d

    ....(4)

Now multiplying (4) by 4 and subtracting from (1) to eliminate h

f = $1.04

Now

h = $2.58

We know

Substituting values of h and f

d = $1.15

Therefore, a hamburger costs $2.58

Fries costs $1.04

Drink costs $1.15

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
