35. let the no. of submarines hit be x

then the total no. of destroyers hit = ( 10 -x)

so the total no. of points = 36

so (10 -x) * 5 + 3*x = 36

on solving we get x = 7

so the total no. of submarines hit = 7

36. let the no of flags and pom pom be x

so the total budget = 5.20 * x + 0.80 *x+ 47 = 377

37. let the no of pom poms be x

then the no of flags =2x

38. let the weekly allowance be x

then money spent on golf = 0.5 x

money earned by car washing = 15

so x - 0.5x + 15 = 32.50

so x= 35

so her weekly allowance is $35

David has 175

Bill has 50
