You and a friend decide to sell cookies to raise money for a local fundraiser. after you have raised (9 d + 10) dollars and your friend has raised (8d + 5) dollars. write an expression that represents the total amount of money that you raised together?

The total money raised by two Friends in fundraiser is $ ( 17 d + 15).

Step-by-step explanation:

Money raised by one friend  = $ (9 d + 10)

Money raised by other friend  =  $ (8 d + 5)

Now, Total Money raised together

= Money Raised by friend 1 + Money raised by friend  2

= $ (9 d + 10)   +   $ (8 d + 5)

= ( 9d + 8d) + ( 10 + 5)

= 17 d  + 15

or, Total Money  = ( 17 d  + 15 )

Hence, the total money raised by two Friends in fundraiser is $ ( 17 d + 15).

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
