The amount of money raised at a school fundraiser is directly proportional to the number of people who attend. last year the amount of money raised for 100 attendees was $2500. how much money will be raised is 875 people attend this year?

Amount of money raised for 875 people=A=$21,875

Step-by-step explanation:

This can be expression in the equation, A=k.N;

Where;

A=Amount of money raised=$2500

k=Constant of proportionality(Amount of money per attendee)

N=Number of attendees=100

Replacing in the expression;

Amount of money raised=K×Number of people who attend

2500=K×100

K=(2500/100)=25

Amount of money per attendee=K=$25 per attendee

How much money was raised for 875 people?

Using the expression, A=k.N

where;

Number of people (N)=875

k=25

Replacing;

A=(25×875)=$21,875

Amount of money raised for 875 people=A=$21,875

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
