Answer:
The total portions of salad she makes is 30.
Explanation:
Given:
Nicole takes 2/5 of a pound of tuna to make 5 portions of salad. She uses 1 1/5 pound of canned tuna for every two onions used.
Now, to find the total portions of salad she make.
For 2 onions she used = 1 1/5 pound of tuna that is 6/5 pound.
So, for 1 onion = 6/5 ÷ 2 = 3/5.
And for 4 onions = 3/5 × 4 = 12/5 pound of tuna.
Now, she takes 2/5 pound of tuna for 5 portions.
So, 1 pound of tuna = 5 ÷ 2/5 = 25/2 portions.
So, according to question:
Total portions of salad = total pound of tuna × total portions.
=

=

=
Therefore, total portions of salad she make is 30.
