Last year you mowed and shoveled snow for 10 households. you earn $200 per household mowing for the entire season and $180 per household shoveling for the entire season. you earned a total of $1,880 last year. write and solve an algebraic model to determine the number of households you mow and shovel for.

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
