Q. The expression 20l+25g−10 gives the number of dollars that Josie makes from mowing l lawns and raking g gardens. How many dollars does Josie make from raking 4 gardens and mowing 3 lawns?□
Given Expression: We are given the expression 20l+25g−10, where l represents the number of lawns mowed and g represents the number of gardens raked. We need to calculate the total amount Josie makes for raking 4 gardens and mowing 3 lawns.
Substitute Values: Substitute l with 3 and g with 4 into the expression to find the total amount of money made.Total amount = 20(3)+25(4)−10
Perform Multiplication: Perform the multiplication for each term.Total amount = (20×3)+(25×4)−10Total amount = 60+100−10
Add and Subtract: Add and subtract the numbers to find the total amount.Total amount = 60+100−10Total amount = 160−10Total amount = 150
