Answer:


Step-by-step explanation:

Let each turkey sandwich cost x, and the fixed delivery fee be y.

From the first situation, 4x + y = 33

From the second case with 8 sandwiches, 8x + y = 61

Subtracting the first equation from the second gives 4x = 28

x = 7

Substituting this back into the first equation gives y = 5.

Therefore, each turkey sandwich costs $7 and the delivery fee is $5.

If you were to have 12 turkey sandwiches delivered, the cost would be 12x + y = 12*7 + 5 = $89, so this would be more than $85.


If you want to do it graphically, convert both equations into slope-intercept form.

y = -4x + 33 and y = -8x + 61

For the first equation, the y-intercept is (0,33) and the x-intercept is (33/4, 0).

For the second equation, the y-intercept is (0,61) and the x-intercept is (61/8, 0).

Connect the intercepts for each equation, then find the point of intersection. The x- and y-coordinates of the point of intersection are x = 7 and y = 5, which are the values that will solve the equations.

nikitadnepr [17]

Answer:

The jeweler made 11 bracelets and 7 necklaces.

Step-by-step explanation:

Given that a jeweler had a fixed amount of gold to make bracelets and necklaces, and the amount of gold in each bracelet is 6 grams and the amount of gold in each necklace is 16 grams, knowing that the jeweler used 178 grams of gold and made 7 more necklaces than bracelets, to determine a system of equations that could be used to determine the number of bracelets made and the number of necklaces made, the following mathematical reasoning should be considered:

(16 - 6) x 7 = 70

178 - 70 = 108

108/6 = 18

18 - 7 = 11

(11 x 6) + (7 x 16) = X

66 + 112 = X

178 = X

Thus, the jeweler made 11 bracelets and 7 necklaces.
