15x = 18(x-.10)
x = .60
15*.60 = $9.00
18*.50 = $9.00

1 orange + $0.10
(1 orange + $0.10) * 15
= 15 pears + ( 15 * $0.10)
= 15 pears + $1.50
15 pears + $1.50 = 18 oranges (Cost of 15 pears = Cost of 18 oranges)
18 oranges - 15 pears = 3 oranges
3 oranges —> $1.50
1 orange —> $0.50
1 pear —> $0.50 + $0.10 = $0.60
15 pears —> $0.60 * 15 = $9
Willy spent $9 on the 15 pears.
(1 orange + $0.10) * 15
= 15 pears + ( 15 * $0.10)
= 15 pears + $1.50
15 pears + $1.50 = 18 oranges (Cost of 15 pears = Cost of 18 oranges)
18 oranges - 15 pears = 3 oranges
3 oranges —> $1.50
1 orange —> $0.50
1 pear —> $0.50 + $0.10 = $0.60
15 pears —> $0.60 * 15 = $9
Willy spent $9 on the 15 pears.
