Answer:

0 boxes minimum

The mass of the truck and paper must satisfy ...

22.5b + 2948.35 ≤ 4700 . . . . total truck mass cannot exceed bridge limits

22.5b ≤ 1751.65

b ≤ 77.85

The driver can take a minimum of 0 boxes and a maximum of 77 boxes of paper over the bridge.

$\huge\textsf{Hey there!}$

$\bullet \large\textsf{ Finding the mean you have to add up all of your numbers \& divide it}\\\large\textsf{by the total numbers in your data plot}$

$\mathsf{\dfrac{20 + 5 + 45 + 90 + 60 + 45 + 30 + 10 + 20+ 45 + 15 + 25}{12}}$

$\mathsf{20 + 5 + 45 + 90 + 60 + 45 + 30 + 10 + 20+ 45 + 15 + 25}$

$\mathsf{= 25 + 45 + 90 + 60 + 45 + 30 + 10 + 20 + 45 + 15 + 25}$

$\mathsf{= 70 + 90 + 60 + 45 + 30 + 10 + 20 + 45 + 15 + 25}$

$\mathsf{= 160 + 60 + 45 + 30 + 10 + 20 + 45 + 15 + 25}$

$\mathsf{= 220 + 45 + 30 + 10 + 20 + 45 + 15 + 25}$

$\mathsf{= 265 + 30 + 10 + 20 + 45 + 15 + 25}$

$\mathsf{= 295 + 10 + 20 + 45 + 15 + 25}$

$\mathsf{= 305 + 20 + 45 + 15 + 25}$

$\mathsf{= 325 + 45 + 15 + 25}$

$\mathsf{= 370 + 15 + 25}$

$\mathsf{= 385 + 25}$

$\mathsf{= \bf 410}$

$\mathsf{= \dfrac{410}{12}}$

$\mathsf{\dfrac{410}{12} \approx \bf 34.1667}$

$\boxed{\boxed{\huge\textsf{Thus, your ANSWER is: \boxed{\mathsf{ \bf \underline{{\star 34.1667\star}}}}}}}}\huge\checkmark$
