Sagot :

Answer:

1. 450

2. 8(12)+3(2.50)

3. 10

4. 32

Step-by-step explanation:

1. 700-250=450

2. 8 people going to the theater. If tickets cost $12 each, you multiply 8 by 12 to get the ticket cost. If 3 people ordered drinks and drinks cost $2.50, you multiply 3 by 2.50 to get the drink cost. Since this is asking for the total cost you add your first 2 answers to get the final cost.

3. 12/3=4, which means one pound costs $4. To find the amount bought with $40, divide 40 by 4, which equals 10 pounds.

4. To find percents, you turn your percentage into a decimal by dividing by 100. (400/100=4), then you multiply that by the number you are trying to find a percentage of(8x4=32). This gives you the answer 32.
