The directions here are: Write a proportion as your first step in solving each problem.

the steak costs $\displaystyle \frac {\$ 1.74}{8 \text{ ounces}}$now what do you have to multiply this by to get 12 ounces in the denominator? or better yet, since the cost per unit ounce is to remain constant, write$\displaystyle \frac {\$1.74}{8 \text{ ounces}} = \frac {\$ x}{12 \text{ ounces}}$, now solve for x 3. ## Thanks, however there's more Ok, the answer i have is c$1.74

12 = 8

but how do i solve this?

c $1.74 12 = 8 but how do i solve this? i don't understand what you typed. you are solving$\displaystyle \frac {1.74}8 = \frac x{12}$for$\displaystyle x$5. ## .. the easiest way to think about it is do$1.74 / 8 to get the value of a 1 ounce steak and then times that by 12 to getthe value of a 12 ounce steak

6. 1.74 x
8 = 12

Now, cross multiply: 8x = 1.74 x 12
Multiply: $\displaystyle 8x = 20.88$
Divide by 8: x = \$2.61
