please help me find out the answer I am request you to find out the answer do all​

Answer 1

Answer:

sorry I only remembered how to do 7 and 6

Step-by-step explanation:

FOR 7

you are basically finding how much of the percentage of students out of 1200 are going on the picnic so you will do

240÷1200 x 100

=20%

FOR 9

you have to basically increase the person salary by 8.5%

1) First convert the percentage into decimals

8.5÷100 = 0.085

Now also 100% into decimal

100÷100 = 1

2) Now add the decimals since it's a increase

1 + 0.085 = 1.085

3) Now multiply 1.085 by the person's salary( 12,000)

1.085 × 12,000 = 13,020

*13,020 is the person's new income*
