ashton is saving money to buy a new bike.he needs $120 but has only saved 60% so far how much money does ashton need to buy the scooter?

Answers

Answer:

Ashton needs $48 to buy the bike

Step-by-step explanation:

The cost of the bike is $120. In this moment Ashton has saved 60 % to convert it to money we have to multiply the cost of the bike and the percentage saved and divide it by 100 % to eliminate the percentage units.

(120 * 60)/(100)= 72

So in this moment Ahston has save $72 for the bike. Now, we just have to substract the total cost of the bike and the saved money.

120 - 72 = 48

Ashton needs $48 to buy the bike
120 x .60 =72


or in fraction form it would be  120/1 x 60/100 = 7200/100 which simplifies to 72.

So the answer would be 120- 72 = $48
