The first option is correct. See an explanation below.
We are given : $168 raised for washing 24 cars and $280 raised for washing 40 cars.
We know the rate formula.
Rate = Total amount ÷ Total numbers.
Let us find value of each rate for the given problem.
Rate 1: Total amount ÷ Total numbers = $168 ÷ 24 = $7.
Rate 2: Total amount ÷ Total numbers = $280 ÷ 40 = $7.
We can clearly see that Rate 1 is equal to Rate 2, that is $7.
So, we can say rates are equivalent.
It’s 2x3x3x5 because 9 isn’t prime
Step-by-step explanation:
For number 5 the answer would be <em>economy</em> because there is a <u>2 dollar difference</u> and the shampoo bottle has 20 more ounces then the <em>regular</em> bottle. The <u>2 dollar difference</u> changes the whole thing.
For number 6 the answer is still <em>economy</em> because you get more ounces in the bottle of shampoo for a <u>3 dollar difference</u> in the price.
