Question

Dallas and Lex both have money in the bank. Dallas has $120 and is taking

$10 out each week. Lex has $30 in his account and is saving $5 each week.
Which set of equations models this situation?

Answer 1

D = 120-10W

L = 30+5W

Explanation:

D = 120-10W

L = 30+5W

Dallas and Lex are both doing this in weeks, so we can use W as weeks. 120-10W indicates he takes out 10 a week, starting at 120. Lex starts at 30 and adds 5 a week.
