5/6×y=25
Y= -5/6+25
Y = 24.16667 or 24 1/6
Answer:
The combined cost of 1 pound of salmon and 1 pound of swordfish is $16.60
Step-by-step explanation:
Let $x be the cost of 1 pound of salmon.
The swordfish costs $0.20 per pound less than the salmon, then $(x-0.20) is the cost of 1 pound of swordfish.
Melissa buys 2.5 pounds of salmon and pays $2.5x for salmon.
Melissa buys 1.25 pounds of swordfish and pays $1.25(x-0.20) for swordfish.
She pays a total of $31.25, then
Solve this equation.
Costs:
1 pound of salmon - $8.40
1 pound of swordfish - $8.20
Combined - $16.60
Since you have the slope, you can start your equation with y= -8/7x +b. To find b, plug the X value for the point you were given in for the X (-8/7•4) you get -32/7 or -4.57. Then you take the given Y value(4) and subtract the number you just found (4-(-4.57)). You get 8.57. That means your equation is Y= -8/7 + 8.57
