Tim$4.81,Paul$5.42,Peter$3.94 With Al's,each have an avg of $5.00 each.how much al has?

Question

a.$6.03
b.$5.83
c.$5.17
d.$5.00
e.$4.72

Answer 1

Let x = the amount of money that Al has.  The average, or arithmetic mean, for all four boys is:

 

($4.81 + $5.42 + $3.94 + x)/4 = $5.00

 

($14.17+x)/4 = $5.00

 

$14.17 + x = $20.00

 

Solve for x.
