Answer:
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).
