Traci
collects money for a dance marathon.
=> One group of sponsors donate $6 per hour she dances.
=> Another group donates $75 no
matter how long she dances.
Find out what number of hours does she have to dance to the nearest minute in
order to collect at least $1000
Formula:
=> 75 dollars + 6x = 1000 dollars
=> 6x = 1000 – 75
=> 6x = 925
=> 6x / 6 = 925 / 6
=> x = 154.17
Let’s check
=> 154.17 * 6 = 925 + 75 = 100
