Cody was 160 cm. Tall on the first day of school this year, which was 10% taller than he was on the first day of school last year. How tall was Cody on the first day of school last year?

Let X = height of Cody on the first day of school last year

Given: Y= height of Cody on the first day of school year = 160 cm

10%(X)+X=Y

.10(X)+X=160

1.10X=160

X=160/1.1

X= 145.45.cm = height of Cody on the first day of school last year

Hope it helps
