Answer:
8$
Step-by-step explanation:
If strawberries cost $2 per pound and she buys 5 pounds we have to multiply the cost of 1 pound by 5.
[tex]2.5= 10[/tex]
The discount of 20% is applied to the $ 10, we calculate how much the value of 20% (using a simple rule of three) is and subtract it from $ 10.
[tex]100\longrightarrow 10\\ 20\longrightarrow x\\ x=\frac{20.(10)}{100}= 2[/tex]
[tex](10-2)=8[/tex]
