Question

A racket and 4 birdies cost $13.75. The racket costs $5.50 more than each birdie. Find the cost of the racket.

Answer 1

r+ 4b = $13.75

r = $5.50 + b

$5.50 + b + 4b = $13.75
$5.50 + 5b = $13.75
$5.50-$5.50 +5b = $13.75-$5.50
5b = $8.25
5b/5 = $8.25/5
b = $1.65

r = $5.50 + $1.65
r = $7.15
A racket cost $7.15

Check
$7.15 + 4($1.65) = $13.75
$7.15 + $6.60 = $13.75
$13.75 = $13.75
