Patterns can be used to determine products of a number of a power of 10 by following it to obtain easily the answer. When you multiply a number by the power of 10 you just have to write the number then add the number of corresponding number of 0s to the end which will be the same number as the power used.

Ms. Banerjee bought a car for $22,500. The amount she paid for her new car was twice the amount she paid for her previous car, w
bagirrra123 [75]

You didn't say if the car bought is the new car or the old car so I'm assuming the car bought for $22,500 is the new car.

You divide 22,500 by 2 to get the cost of the old car. When you do this, you find out the old car costed $11,250.

the equation is 22,500/2=p


If $22,500 is the cost of the old car, then it's not my fault that the poster did not make it clear. If the previous car costed $22,500, then the previous car costed $22,500
