Allen's daily regular wage is P1,420. This coming Christmas, his boss is asking him to work for 14 hours. How much is his DAILY

VMariaS [17]

Using proportions, it is found that his DAILY RATE on that particular day is of Php 2,420 .

This question is solved by proportions, using a rule of three.

In a regular 8-hour day, Allen earns Php 1420. How much will he earn on a 14 hour day?

The rule of three is:

8 hours - Php 1420

14 hours - x

Applying cross multiplication:

$8x = 1420 \times 14$

$x = \frac{1420 \times 14}{8}$

$x = 2485$

The closest option is Php 2,420.

What is the slope-intercept equation of the line that includes (0,7) and (3,10)?

$\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{7})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{10}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{10-7}{3-0}\implies \cfrac{3}{3}\implies 1 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-7=1(x-0)\implies y-7=x\implies y=x+7$
