Alicia runs a small business mowing yards in the summer. For every yard she mows, she earns $40. However, she spends part of this money on gasoline for her lawnmower. Each gallon of gasoline costs $3. Write an expression for the amount of money that Alicia earns in a day, where y is the number of yards she mows and g is the number of gallons of gasoline she buys. $40g + $3y

$40y + $3g

$3g − $40y

$40y − $3g

$40y - $3g

Step-by-step explanation:

it wouldn't be c because the 3 and 40 are on the wrong side. and it wouldn't be a because the y and g are on the wrong number. you should realise that the variables y and g need to go to the corresponding amount and $40 is how much she get by mowing lawns (y) and $3 is how much gasoline costs to take away from her total amount. so its now between b and d. it is d because you are subtracting 3 from 40 because that how much she spent and it takes away from her total.
