b. Next week, Mr. Lee will double the number of boxes he orders. Write a new expression to represent the number of oranges in next week’s order.
c. Evaluate your expression from Part (b) to find the total number of oranges ordered in both weeks.

Answer 1

a)480

b)960

c)1440

Explanation:

We are given the following information:

Number of oranges in a box = 24

a)Boxes ordered by Lee for his store = 8

Number of boxes ordered by Lee for his restaurant = 12

Total number of oranges ordered = Total number of boxes ordered × Number of oranges in 1 box

`= (8+12)* 24 = 20* 24 = 480`

b) Now Mr. Lee doubled his order for next week.

Boxes ordered by Lee for his store = 16

Number of boxes ordered by Lee for his restaurant = 24

Total number of oranges ordered = Total number of boxes ordered × Number of oranges in 1 box

`= (16+24)* 24 = 40* 24 = 960`

c) Total number of oranges ordered =

`(20* 24) + (40* 24) = (20+40)* 24 = 1440`

Therefore, total 1440 oranges were ordered by Mr. Lee.
