Answer 1

The equation for the expenses of the bakery is $800+$10t, where t is given in hours. On the other hand, the equation that models the receipts is $90t, where t is in hours.

To find the value of t such that the expenses are equal to the receipt we need to solve the equation below

`\begin{gathered} 800+10t=90t \\ \Rightarrow800=90t-10t=80t \\ \Rightarrow t=10 \end{gathered}`

In dollars, this is

`90\cdot10=900`

The answer is $900 dollars

The graph of the equations is

The green line represents the expenses and the blue one the receipts
