<span>The parking meter charges $2 per hour, means that each half hour costs $1.
Thus, 1$ pays for half an hour, so d $ pay for d half hours, that is d/2 hours, which is 0.5d hours.
15 minutes a quarter of an hour, which is 0.25 h.
Thus, the driver has a total of d/2 hours that she payed for, + 1/4 hour from the previous driver. These make a total of 3 hours, so we can set the equation:
3=0.5d+0.25
Answer: B</span>
Step-by-step explanation:
In triangle
x²=5²+12²
x²=25+144
x²=169
x= root of 169
x=13
So, personally I would take 252 and divide it by 4. this will give you 63 which is 1/4 of the cookies. Then add that 63 three times to get a total of 189 cookies which would be your 3/4 sold. so since there is only 63 cookies left then you would go into your final problem. 3/9 is equal to 1/3, so all you would do is divide 63 by 3 and get a total of 21 cookies given to the pta.
