Question

Company produces three products
every day. Their total production on
a certain day is 45 tons. It is found
• that the production of the third
product exceeds the production of
the first product by 8 tons while the
total combined production of the
first and third product is twice that
of the second product. Determine
the production level of first product
using Cramer's rule.
Select one:​

Answer 1

First product = x

Second product = (2x+8)/2 = x + 4

Third product = x + 8

Adding all three , we get,

x + x + 4 + x + 8 = 45

3x + 12 = 45

3x = 33

x = 11

First product = 11 ton

Second product = 15 ton

Third product = 19 ton
