Question

A certain country has 291 million acres of forest. Every year, the country loses 3.88 million acres of forest mainly due to deforestation for farming purposes. If this situation continues at this pace, how many years later will the country have only 120.29 million acres of forest left? (Use an equation to solve this problem.)

After ______ years, this country would have 120.28 million acres of forest left.

Answer 1

44 years

Explanation:

291-3.88x=120.28 x equals years

291-291-3.88x=120.28-291

-3.88x=-170.72

-3.88/-3.88x=-170.72/-3.88

x=44

Answer 2

• Rate of decrease=3.88M
• Initial=291M

Equation in slope intercept form

• y=mx+b
• y=-3.88x+291

Now

• 120.29=-3.88x+291
• -3.88x=120.29-291
• -170.71=-3.88x
• x=43.997≈44years
