Calculation of Remaining Magazines to Sell

To calculate the number of magazines that are left to sell, we need to subtract the number of magazines sold from the total number of magazines delivered.

Given that 34 magazines were delivered and 20% of them were sold before noon, we can calculate the number of magazines sold as follows:

Number of magazines sold = Total number of magazines delivered * Percentage sold

Number of magazines sold = 34 * 0.20 = 6.8

Since we cannot have a fraction of a magazine, we need to round down to the nearest whole number. Therefore, 6 magazines were sold before noon.

To find the number of magazines that are left to sell, we subtract the number of magazines sold from the total number of magazines delivered:

Number of magazines left to sell = Total number of magazines delivered - Number of magazines sold

Number of magazines left to sell = 34 - 6 = 28

Therefore, there are 28 magazines left to sell.
