Answer:
3 lb
Step-by-step explanation:
By the given diagram,
The weight of,
First container = 1.03 lb,
Second container = 1.12 lb,
Third container = 1.6 lb,
Thus, the total weight of the containers of potato salad = 1.03 + 1.12 + 1.6 = 3.75 lb,
∵ she brings 4/5 of the potato salad to a picnic,
So, the total potatoes salads taken for the picnic = [tex]\frac{4}{5}\times 3.75[/tex]
= 4 × 0.75
= 3 lb,
Alternative method :
'She brings 4/5 of the potato salad to a picnic' states that 4/5th of each container is taken,
[tex]\frac{4}{5}[/tex] of first container = [tex]\frac{4}{5}\times 1.03[/tex] = 0.824 lb,
[tex]\frac{4}{5}[/tex] of second container = [tex]\frac{4}{5}\times 1.12[/tex] = 0.896 lb,
[tex]\frac{4}{5}[/tex] of third container = [tex]\frac{4}{5}\times 1.6[/tex] = 1.28 lb,
Hence, the total potato salad is taken for the picnic
= 0.824+0.896+1.28
= 3 lb
