Tony worked 4 2/3 hours on his science project. Sonia worked 1 1/4 times as long on her science project as Tony did.For how many

kherson [118]

To find how many hours Sonia work on her science project,we can multiply the working hours of Tony by the times Sonia did:

$4 \frac{2}{3} \times 1 \frac{1}{4} \\ = \frac{14}{3} \times \frac{5}{4} \\ = \frac{70}{12} \\ = 5 \frac{10}{12} \\ = 5 \frac{5}{6}$
Therefore Sonia work on her science project for 5 5/6 hours.

Hope it helps!

It costs $107 for 10 students and $137 for 15 students. How much does it cost for 12 students?

Anestetic [448]

$\bf \begin{array}{ccccccccc}
&&\stackrel{students}{x_1}&&\stackrel{price}{y_1}&&\stackrel{students}{x_2}&&\stackrel{price}{y_2}\\
% (a,b)
&&(~{{ 10}} &,&{{ 107}}~) 
% (c,d)
&&(~{{ 15}} &,&{{ 137}}~)
\end{array}
\\\\\\
% slope = m
slope = {{ m}}\implies 
\cfrac{\stackrel{rise}{{{ y_2}}-{{ y_1}}}}{\stackrel{run}{{{ x_2}}-{{ x_1}}}}\implies \cfrac{137-107}{15-10}\implies \cfrac{30}{5}\implies \cfrac{6}{1}\implies 6$

$\bf \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-107=6(x-10)
\\\\\\
y-107=6x-60
\implies 
y=6x+47\\\\
-------------------------------\\\\
\textit{how much will it be for }\stackrel{x}{12~students?}\qquad y=6(12)+47$
