C. 30.00 - (1.79a + 0.36b + 2.99)      (I think that's correct)

Answer:

[tex]30-(1.79a+0.36b+2.99)[/tex]

Step-by-step explanation:

Let  a represents the number of pounds of apples Abigail buys

Cost of 1 pound of apple = $1.79

So, Cost of a pounds of apple = 1.79a

Let b represents the number of bananas she buys,

Cost of 1 pound of banana = $0.36

Cost of b pounds of banana = 0.36b

Abigail buys 3 pounds of potatoes

Cost of 3 pounds of potatoes = $2.99

So, Total cost = [tex]1.79a+0.36b+2.99[/tex]

Abigail has $30.00 to buy groceries.

So, the amount of change she receives after her purchases=[tex]30-(1.79a+0.36b+2.99)[/tex]

So,Option C is correct.

Hence The  expression represents the amount of change she receives after her purchases is [tex]30-(1.79a+0.36b+2.99)[/tex]
