1x1 =
1 u |
10 u - 8 |
The number of biscuits at first is repeated. Make the number of biscuits at first the same. LCM of 3 and 6 is 6.
Total number of pastries left
= 1 u + 10 u - 8
= 11 u - 8
11 u - 8 = 80
11 u = 80 + 8
11 u = 88
1 u = 88 ÷ 11 = 8
Number of pastries that Neave sold
= 5 u + 8
= 5 x 8 + 8
= 40 + 8
= 48
Answer(s): 48
