The expression 20 l+25 g-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? ◻ dollars

Identify Given Values: Identify the given values from the problem. Josie makes a certain amount of money for each lawn mowed (l) and each garden raked (g). The expression for calculating the total amount of money made is 20l + 25g - 10. We are given that Josie rakes 4 gardens and mows 3 lawns. Number of lawns mowed (l) = 3 Number of gardens raked (g) = 4Substitute Given Values: Substitute the given values into the expression. Using the expression 20l + 25g - 10, we substitute l with 3 and g with 4. Total amount made = 20(3) + 25(4) - 10Perform Multiplication: Perform the multiplication. Calculate the amount made from mowing lawns: 20 * 3 = 60 Calculate the amount made from raking gardens: 25 * 4 = 100Add and Subtract: Add the amounts and subtract the constant. Now, add the amounts from mowing and raking, then subtract 10. Total amount made = 60 + 100 - 10Find Final Amount: Perform the addition and subtraction to find the final amount. Total amount made = 160 - 10 Total amount made = 150

Identify Given Values: Identify the given values from the problem. $\newline$ Josie makes a certain amount of money for each lawn mowed $l$ and each garden raked $g$ . The expression for calculating the total amount of money made is $20l + 25g - 10$ . We are given that Josie rakes $4$ gardens and mows $3$ lawns. $\newline$ Number of lawns mowed $l$ = $3$ $\newline$ Number of gardens raked $g$ = $4$
Substitute Given Values: Substitute the given values into the expression. $\newline$ Using the expression $20l + 25g - 10$ , we substitute $l$ with $3$ and $g$ with $4$ . $\newline$ Total amount made = $20(3) + 25(4) - 10$
Perform Multiplication: Perform the multiplication. $\newline$ Calculate the amount made from mowing lawns: $20 \times 3 = 60$ $\newline$ Calculate the amount made from raking gardens: $25 \times 4 = 100$
Add and Subtract: Add the amounts and subtract the constant. $\newline$ Now, add the amounts from mowing and raking, then subtract $10$ . $\newline$ Total amount made = $60 + 100 - 10$
Find Final Amount: Perform the addition and subtraction to find the final amount. $\newline$ Total amount made = $160 - 10$ $\newline$ Total amount made = $150$
