Sierra borrows $310 from her brother to buy a lawn mower. She will repay $85 to start, and then another $25 per week. A. Write an equation that can be used to determine w, the number of weeks it will take for Sierra to repay the entire amount.

Let w be the number of weeks. We have the equation:
25w + 85 = 310

Type this equation into the search engine, and we get:
w = 9
