the shorter sides are 4 inches and the longer sides are 21 inches long
So first you would divide 1950/6 to find the amount for one year of their age.
Then you would multiply that by the ages, which should get you 4 numbers, then you all those numbers together. Try 9750.
40%=0.4
0.4+1=1.4
4.5(1.4)=6.3
The answer is $6.30
