One product increased by 50% followed by 20%, reaching a value of 1200.00. Ask yourself how much is the initial value of this product? benzóico.

Assuming 'increased by' means 'increased in price by', Initial value = x. Increase by 50% > 1.5x. Further increase by 20% > 1.2*1.5x x = 2000/3.

666.67 * 1.5 = 1000.00 * 1.2 = 1200.00 If you still have questions, ask your teacher...

Então 1200 é o valor final, então divide 1200/1,8 ? que da 666,6666667? (e esse 1,8" é do acréscimo? 50= 1+0,5 20=1+0,2?
