Given:
Factory expenses = $1900
Cost of each toy truck, t = $11
Selling price of each truck = $30
The equation for this will be:
30t = 1900 + 11t
The equation in terms of t:
First subtract 11t from both sides
30t-11t = 1900+11t-11t
30t-11t = 1900
t(30-11) = 1900
The equation in terms of t is:
![t\text{ = }(1900)/(30-11)](https://img.qammunity.org/2023/formulas/mathematics/college/7mo4fyx0vkaj8m0fza5zwg5xmwprv8ubrv.png)
