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?

Josie makes $150 from raking 4 gardens and mowing 3 lawns.

Given:

Expression: 20l + 25g - 10

l = 3

g = 4

20 (3) + 25 (4) - 10

60 + 100 - 10

160 - 10 = 150

So,

20l + 25g - 10

"l" represents the number of lawns Josie mows, while "g" represents the number of gardens Josie rakes. Substituting the given values into the expression, we get:

20 (3) + 25 (4) - 10

Simplify.

60 + 100 - 10

160 - 10

150

Josie makes $150 from raking 4 gardens and mowing 3 lawns.
