Answer:
Step-by-step explanation:
50 times 4/5 is 40. meaning we subtract the two to find the unsold
50-40 = 10
so 10 guavas were left unsold
2/3 is equal to 8/12 and 3/4 is equal to 9/12
3.79 + .79 + .99 = 5.57
So the entire lunch costs $5.57

Answer:
5 years
Step-by-step explanation:
1. if able's age is x, then his sister's is x-4, and his brother's is 2x
2. if these sum to 32, then we can formulate the equation x+(x-4)+2x=32
3. now solve for x, 4x-4=32, 4x=36, x=9
4. if able's sister is x-4 years old, she is 9-4, or 5 years old
You would do 100-30 because 30 is what you have left and 100-30 is 70 so $70 was lost
