3(a - 4) ≤ 33

<u>Step 2: Solve for </u><em><u>a</u></em>

  1. Divide 3 on both sides:                    a - 4 ≤ 11
  2. Add 4 on both sides:                        a ≤ 15

Here we see that any value <em>a </em>less than or equal to 15 would work as a solution to the inequality.

Help guys show your solution​
Ivahew [28]

Answer:

Profit =\frac{80p + 170}{p}

Step-by-step explanation:

Cost of the Yield = \frac{100p + 200}{p}

Cost of the labour = \frac{10p + 50}{p}

Cost of the fertilisers = \frac{10p - 20}{p}

Total expenses = \frac{10p + 50}{p}  +  \frac{10p - 20}{p}  =  \frac{20p + 30}{p}

Profit = Total expenses - Cost of yield

=  >  \frac{100p + 200}{p}  -  \frac{20p + 30}{p}

=  >  \frac{80p + 170}{p}
