You have a summer job detailing cars. you charge $5 to wash a car, $25 to wax a car, and $2 to vacuum a car. what algebraic expression models the total amount you can earn? if you wash 8 cars, wax 2 cars, and vacuum 6 cars, how much will you earn in all?

algebraic expression models the total amount you can earn .

You earn $102 in total If you wash 8 cars, wax 2 cars, and vacuum 6 cars

Step-by-step explanation:

Let x be the no. of cars you washed

Cost of washing 1 car = $5

Cost of washing x cars = 5x

Let y be the no. of cars waxed

Cost of waxing 1 car = $25

Cost of waxing y cars = 25y

Let z be the no. of cars vacuumed

Cost of vacuuming 1 car = $2

Cost of vacuuming z cars = 2z

Let T be the total cost

So,

So, algebraic expression models the total amount you can earn .

Now we are supposed to find that you wash 8 cars, wax 2 cars, and vacuum 6 cars, how much will you earn in all?

x = 8

y= 2

z=6

Substitute the value in the expressions

Hence You earn $102 in total If you wash 8 cars, wax 2 cars, and vacuum 6 cars

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
