Jim works at a furniture shop. he can assemble 88 chairs in 22 hours. if he can assemble c chairs in 1 hour, identify the equation that can be used to find the value of c. 22 x c = 88 88 x c = 22 88 + c = 22 88= c + 22 22 + 88 = c

first option 22×c = 88

Justification:

This problem may be solved by setting a proportion.

A proportion is the equality of two ratios.

Here the first ratio is the number of chairs that Jim can assemble in 22 hours:

  88 chairs
  
22 hours.

The second ratio is the number of chairs (c) that he can assemble in 1 hour:

   c

1 hour

Then, when you equal both ratios you get the proportion:

88 chairs         c
=
22 hours      1 hour

Solving for c, you get: c × 22 = 88, wich is the first option.
