Answer 1

Calculating the amount spent by Kevin during the entire school year:

Given,

Money spent during one week is $\$11.25$

Applying the unitary method, we can write

Money spent during $35.5$ weeks will be,

$$\begin{gathered} =11.25\times 35.5 \\ =\$399.375 \\ =\$399 \end{gathered}$$

Hence, the total amount spent by Kevin during his entire school year is $\$399$
