Lesson Summary

Jasmine had 6 more sweets than Njoki. Atieno had one third as many sweets as Jasmine. The three girls had a total of 22 sweets. If Njoki had x sweets, which one of the following equations represents the information given in this question?

A.7x + 24=66
B.7x – 24 = 66
C.3x + 24 = 66
D.6x + 24 = 66

Text Answer

We can tabulate this information as follows:

Total number of sweets = x+6+x+13(𝑥+6)= 2x +6+13(𝑥+6)

2x +6+13(𝑥+6)=22

Multiply all terms by 3: 6x + 18 + x + 6 = 66

7x + 24 = 66

The correct answer is A (7X + 24= 66).
