In Clayton County there is a $30 base charge for a speeding ticket. For every mile per hour the drive travels above the speed limit, there is an additional $5 charge. If the speed limit $20 miles per hour and Paul was charged $105 for a speeding ticket, how fast, in miles per hour, was Paul driving.?

Answer 1

在克莱顿县有30美元的收费是驾车超速罚单的基础。每小时每英里以上驱动旅行速度限制,有额外的5元的费用。如果速度限制$ 20英里每小时和保罗被指控为105美元超速,有多快,多少英里每小时,保罗驾驶。

Answer 2

$30 base charge + additional $5 charge*(how fast, in miles per hour- speed limit $20 miles per hour)=$105 for a speeding ticket

simple calculation:
30+5*(x-20)=105
x=35
35 miles per hour

Answer 3

孩子、你不知道混理科的人很少有文科也好的么？

Answer 4

20+（105-30）/5=$35

Answer 5

(105-30)/5=15
20+15=35
