Sara has been trying to make sense of the growth chart her son’s pediatrician has shown her during the last visit. The doctor even gave her a copy to take home so that she can track her son’s growth. At the time of the last visit, 2 months ago, Alistair was at the 75th percentile for length-for-age and at the 25th percentile for weight-for-age.

Today is Alistair’s second birthday, and he is just shy of 35.5 in. tall and weighs 28 lb. Is Alistair growing at the same rate? Using the appropriate growth, chart find out the length-for-age and weight-for-age percentiles for Alistair.

The growth charts can be accessed at the Centers for Disease Control and Prevention (CDC) website or under Hints A1 and A2.

Your answer should have two numbers, the first for length-for-age percentile and the second for weight-for-age percentile. Separate the numbers by a comma. If the crossing point falls between the percentile lines, round the percentile to the nearest line.
