Sergio039 [100]

Step 1

Write out the system of equations

let\text{ x represent pound of Type A coffee and y represent Type B coffee pound }\begin{gathered} 4.30x+5.9y=738.80----(1) \\ x+y=148---(2) \end{gathered}

Step 2

Find the value of one pound of type A coffee, x

\begin{gathered} From\text{ equation 2; x+y=148} \\ Therefore \\ y=148-x \end{gathered}\begin{gathered} Substitute\text{ for y in equation 1} \\ 4.30x+5.9(148-x)=738.80 \\ 4.30x+873.2-5.9x=738.80 \\ 873.2-738.80=5.9x-4.3x \\ 134.4=1.6x \\ x=84pounds \end{gathered}

Therefore the answer will be;

\begin{gathered} x+y=148 \\ 84+y=148 \\ y=64\text{ pounds} \\  \end{gathered}

The pounds of type B coffee she used is 64pounds

The pounds of type A coffee she used is 84 pounds

Petco makes a profit of $9 per bag on its line of natural cat food. If the store wants to make a profit of at least
Nata [24]

Answer:

x ≥ 767

The number of bags sold must be greater than or equal to 767 to make a minimum profit of $6900.

Step-by-step explanation:

If they want a profit of at least $6900, then the total amount earned would have to be ≥ 6900. You can always earn more than $6900, but the lowest should be equal to $6900.

So if we use x as the number of bags sold, and we know that each bag will earn $9, then x • 9 ≥ 6900.

If we divide both sides by 9, then the number of bags sold must be ≥ 767.
