Question 1.
In one year, the factory used 11,650 meters of cotton, 4,950 fewer meters of silk than cotton, and 3,500 fewer meters of wool than silk. How many meters in all were used of the three fabrics?
Answer:
In one year, the factory
Total cotton used = 11,650 meters.
Total silk used = 4,950 m fewer than cotton = 11,650 – 4,950 m
Total wool used = 3,500 m fewer than silk = 11,650 – 4,950 – 3,500 m Question 2.
The shop sold 12,789 chocolate and 9,324 cookie dough cones. It sold 1,078 more peanut butter cones than cookie dough cones and 999 more vanilla cones than chocolate cones. What was the total number of ice cream cones sold?
Answer:
Number of chocolates cone sold = 12,789.
Number of cookie dough cones sold = 9,324.
Number of peanut butter cones sold = 1,078 more than cookie dough cones = 9,324 + 1,078
Number of vanilla cone sold = 999 more than chocolate cones = 12,789 + 999 Question 3.
In the first week of June, a restaurant sold 10,345 omelets. In the second week, 1,096 fewer omelets were sold than in the first week. In the third week, 2 thousand more omelets were sold than in the first week. In the fourth week, 2 thousand fewer omelets were sold than in the first week. How many omelets were sold in all in June?
Answer:
Number of omelets sold In the first week = 10,345
Number of omelets sold In the second week = 1,096 fewer than first week = 10,345 – 1,096
Number of omelets sold In the third week = 2 thousand more omelets than first week = 2,000 + 10,345.
Number of omelets sold In the fourth week = 2 thousand fewer omelets than first week = 10,345 – 2,000 ### Eureka Math Grade 4 Module 1 Lesson 18 Exit Ticket Answer Key
