Question: Mason is a caterer packing up silverware and plates for a big corporate event. Each piece of silverware weighs 4 ounces, and there are three pieces of silverware per setting. Each plate weighs 12 ounces, and there are two plates per setting. If Mason needs enough settings for 15 tables with 8 settings each, plus 20 backup settings in case of breakage, how many ounces will all the settings weigh?
Answer: First find the total weight of the silverware per setting: 4 ounces / piece * 3 pieces / setting = 12 ounces / setting. Then find the total weight of the plates per setting: 12 ounces / plate * 2 plates / setting = 24 ounces / setting. Then add those two amounts to find the total weight per setting: 12 ounces / setting + 24 ounces / setting = 36 ounces / setting. Then multiply the number of tables by the number of settings per table to find the number of table settings: 15 tables * 8 settings / table = 120 settings. Then add the 20 backup settings to find the total number of settings: 120 settings + 20 settings = 140 settings. Then multiply the total number of settings by the weight per setting to find the total weight: 140 settings * 36 ounces / setting = 5040 ounces. The answer is 5040.

Question: Ivan has a piggy bank that can hold 100 pennies and 50 dimes. How much, in dollars, does Ivan have if he has filled his two piggy banks with those coins?
Answer: Ivan has 50 x 10 = 500 cents from the 50 dimes in his one piggy bank. So, he has a total of 100 + 500 = 600 cents in one of his piggy banks. Since 100 cents is equal to 1 dollar, then Ivan has 600 / 100 = 6 dollars from one of his piggy banks. Therefore, Ivan has a total of $6 x 2 piggy banks = $12 from his two piggy banks. The answer is 12.
