Abigail has $30.00 to buy groceries. she needs to buy some apples, some bananas, and 3 pounds of potatoes. fuji apples are $1.79 a pound, bananas are $0.36 each, and potatoes are $2.99 for a 3 lb. bag. if a represents the number of pounds of apples abigail buys and b represents the number of bananas she buys, which expression represents the amount of change she receives after her purchases?

c = [30 - (1.79a) + (0.36b) + 2.99]

Step-by-step explanation:

Abigail has $30.00 to buy groceries.

She needs to buy some apples, some bananas and 3 pounds of potatoes.

The cost of Fuji apples = $1.79 per pound

so the cost of a apples = 1.79 × a = 1.79a

The cost of bananas = $0.36 each

so the cost of b bananas = 0.36 × b = 0.36b

the cost of potatoes for 3 pounds of bag = $2.99

then we will add all the purchase and subtract from $30 to find the amount of change that she received.

the expression will be =

c = [30 - (1.79a) + (0.36b) + 2.99]

yes

step-by-step explanation:

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
