On the first day of the harvest, 186 boxes of oranges were collected. This is 29% less than what was collected on the second day. How many boxes were collected on the second day? (Round the answer to the nearest whole number)

Question:

A
262 boxes

explanation

Step 1: Establish a match

The expression “29% less than on the second day” means that 100% – 29% = 71% of the number of boxes collected on the second day were collected on the first day. Now, we know that 186 is 71% of the number that we are looking for. Let this number be x. We will set up an equation for x and solve it.

Step 2: Set up equalities

First of all, we will define the relationship between values and percentages:

100% = x

and

71% = 186

Step 3: Set up an equation

We will divide the second equation by first equation:

\( \frac{\mathrm{100\% } }{\mathrm{71 \% }} \)= \(\frac{\mathrm{x} }{\mathrm{186} }\)

Remember that you can perform the division only if the corresponding sides of the equations have the same units (e.g. percents must be divided by percents).

Step 4: Solve the equation for x

\(\frac{\mathrm{x} }{\mathrm{186} }\) = \(\frac{\mathrm{100} }{\mathrm{71} }\)

Finally, we will multiply both sides of the equation by 186:

\((\frac{\mathrm{x} }{\mathrm{186} }) × 186\) = \((\frac{\mathrm{100} }{\mathrm{71} }) × 186\)

Or, \(\frac{\mathrm{186x} }{\mathrm{186}} = \frac{\mathrm{18600} }{\mathrm{71} }\)

Or, x = 18600 ÷ 71

= 261.97

Since we are rounding to the nearest whole number, the answer is 262. Therefore, 262 boxes were collected on the second day.
