Using a system of equations, it is found that 22 flowers are in George's garden.

<h3>What is a system of equations?</h3>
  • A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the <em>variables </em>are:

  • Variable x: Number of red flowers.
  • Variable y: Number of blue flowers.
  • Variable z: Number of yellow flowers.

All the flowers are red except 14, that is, there are 14 that are blue or yellow, hence:

y + z = 14 \rightarrow z = 14 - y

All are blue except 18, that is, there are 18 that are red or yellow, hence:

x + z = 18 \rightarrow z = 18 - x

All are yellow except 12, that is, there are 12 that are red or blue, hence:

x + y = 12 \rightarrow y = 12 - x

From the first two equations:

14 - y = 18 - x

x - y = 4

Since y = 12 - x

x - 12 + x = 4

2x = 16

x = 8

y = 12 - x = 12 - 8 = 4

z = 18 - x = 18 - 8 = 10

The total amount of flowers in the garden is:

x + y + z = 8 + 4 + 10 = 22

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 <em>rule of three.</em>
  • In a regular 8-hour day, Allen earns Php 1420. How much will he earn on a 14 hour day?

The <em>rule of three</em> 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.
