a pizza shop sells pizzas that are 10 - inches (in diameter) or larger. a 10 - inch cheese pizza costs $8.50, and each additional topping costs $0.75. write an equation that represents the cost c of a 10 - inch pizza with n toppings.

Answer

planation:

Step1: Identify fixed - cost and variable - cost components

The fixed - cost per acre is the spraying cost, which is $15 per acre. The variable - cost per acre is the sum of seed cost ($115) and additional planting cost ($30), so the variable - cost per acre $v=115 + 30=145$.

Step2: Set up the cost function

The cost function $C(x)$ for $x$ acres is the sum of the fixed - cost and the variable - cost. The fixed - cost for $x$ acres is $15x$ (since it's $15$ per acre), and the variable - cost for $x$ acres is $145x$. So $C(x)=15x+145x$.

Step3: Simplify the cost function

Combining like terms, $C(x)=(15 + 145)x=160x$.

Answer:

$C(x)=160x$
