Question

a new set of slalom I want to see if it's priced at $322.20 which is nine-tenths of the original price find the original price

Answer 1

ok

This is incorrect

`\text{ 322.20 }\cdot\text{ }\frac{9}{10\text{ }}=\text{ }\frac{322.20\text{ x 9}}{10}\text{ = 2899.8/ 10 = 289.98}`

322.20 --------------------- 9/10

x --------------------- 10/10

x = (322.20 x 10/10) / 9/10

x = 322.20 / 9/10

x = 322.20 x 10 / 9

x = 3222 /9

x = 358

The original price is $358
