Mary wants to put all of her stamps on a single page. she has one page with 3 rows of 8 stamps, another page woth 4 rows of 5 stamps, and a third page with 6 rows of 4 stamps. her new single page has 7 rows and can fit 10 stamps across. can she fit all her stamps on the new page? explain.
3*8 = 24
4*5 = 20
6*4 = 24
total stamps: 68
new page holds 7*10 = 70 stamps
To determine if Mary can fit all her stamps on the new single page, we need to find the total number of stamps and compare it to the capacity of the new page. Let's calculate it step by step:
First, we calculate the total number of stamps on each page:
- Page 1: 3 rows of 8 stamps = 3 * 8 = 24 stamps.
- Page 2: 4 rows of 5 stamps = 4 * 5 = 20 stamps.
- Page 3: 6 rows of 4 stamps = 6 * 4 = 24 stamps.
Next, we add up the total number of stamps on all three pages:
24 + 20 + 24 = 68 stamps.
Finally, we need to compare the total number of stamps (68) to the capacity of the new single page (7 rows, 10 stamps per row, for a total of 7 * 10 = 70 stamps).
Since Mary has a total of 68 stamps and the new page has a capacity of 70 stamps, she can indeed fit all her stamps on the new page. Mary will have 2 empty spots on the new page since 70 - 68 = 2.
