Answer

Explanation:

Step1: Analyze option A

The equation in option A should be (50 + 2\times70), not (70+2(50)).

Step2: Analyze option B

Rodney has an initial amount of (70). He mows (2) lawns at (50) each, so the money from mowing lawns is (2\times50 = 100). The total amount is (70+2\times50=70 + 100=170), which matches the given equation.

Step3: Analyze option C

The equation for option C should be (70+50), not (70 + 2(50)).

Step4: Analyze option D

The equation for option D should be (70+50), not (70+2(50)).

Answer:

B. Rodney has $70 in his savings account. He collects $100 for two lawns that he has mowed at $50 each. After Rodney deposited the money collected into his savings account, he has a balance of $170.
