Christopher, age $66$ had been receiving a CPP benefit of $$1050$ per month. Chris passed away suddenly and his wife of $25$ years, Maria, age $65$ is wondering how much she'd be entitled to receive as a survivor benefit. She is currently receiving a CPP benefit of $$850$ per month. If this year's maximum CPP benefit is $$1175\mathrm{.}83,$ how much would Maria receive as the monthly survivor's benefit? $($Do not include and dollar signs and submit your answer to the nearest dollar$).$
