D. 20,000

Answers

Answer:2K

Step-by-step explanation:since one kilogram is 1,000 grams and there 5.1 kL it’s 5,100 grams so about 2,000 pennies

Answer:

C, 2000

Step-by-step explanation:

First convert kilo grams into grams, there are 1000 grams in 1 kilogram, the prefix "kilo" means thousand. if you multiply 5.1 times 1000 you will get 5100 grams in the bag. Divide this by the weight of the penny, 2.5, to get 204. The question asks "About how many pennies are in the bag?" so we know to round to the closest answer being c.

A school allots £1500 to spend on a trip to the theatre.
Theatre tickets have a regular cost of £25 each and are on offer for 1/5 off.
A train ticket for the day will cost £15 each.
If 2 teachers and the maximum number of students attend, how many students go on the trip?

Answers

Answer:

40 students

Step-by-step explanation:

If the tickets are 1/5 that means they cost 4/5

25 * 4/5 = 20

The tickets cost 20 and the train costs 15 so the total per person is 35

Teachers: 2 at 35 = 70

1500 -70 = 1430

Take 1430 / 35 =40.85714286

We can send 40 students

Answer:

Step-by-step explanation:

since the school allots £1500 to spend on a trip to the theatre. Theatre tickets have a regular cost of £35 each and are on offer for 1/5 off

therefore 4/5*35 = 28 for the tickets

A train ticket for the day will cost £15 each.

therefore total cost for each: 28 + 15 = 43 pounds each

If 2 teachers and the maximum number of students attend, how much money will the school have left over?

let s = no. of students

43(s+2) =< 1500

43s + 86 =< 1500

43s =< 1500 - 86

43s =< 1414

s =< 1414/43

s =< 32.88, 32 students max

find how much left over. plus 2 teachers = 34 people

1500 - 43(34) =

1500 - 1462 = 38 pounds left over
