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]

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
