Step-by-step explanation:

we are given

It costs $3.45 to buy lb of chopped walnuts

so,

1 lb of chopped walnuts = $3.45

now, we can multiply both sides by 7.5

7.5\times 1lb=7.5\times 3.457.5×1lb=7.5×3.45

so, we get

7.5 lbs of chopped walnuts = $25.875

So, the cost of 7.5 lbs of chopped walnuts is $25.875
