**The answer gegesmiley34 is:**

because;

when you set up this equation, she has a total of 30 dollars to spend. Since apples are $1.79 per pound, It would be the number of pounds of apples she buys times 1.79. Since bananas are $0.36 each, it would be the number of bananas she buys times 0.36. Since a 3 lb. bag of potatoes is $2.99 and she is only buying 3 pounds of potatoes, she only needs one bag, so add 2.99 to the total.This ends up as 30.00-(1.79a +0.36b+2.99)
