And we have $10 free of taxes.
Making x= number of tires to buy, then we have that the total cost of tires is:

Answer:
The table C
Step-by-step explanation:
when you multiply the x number in the table c by 0.3 you get the same answer as the one in the y column. The constant of proportionality is the value that stays constant in the ratio. Since when you multiply each number in the x column by 0.3 and you always get the number in the y column it shows that the table c is correct.
Answer: Yes, they are equal
Step-by-step explanation:
Quick statement: To find equivalent fractions, multiply or divide them by the same number.
In this particular example, you can divide 182 by 7 and get 26 and 21 by 7 to get 3. This symbols that they are equal. If you try the inverse operation (multiplication), you could multiply 26 by 7 and get 182. Same goes for 21 and 3: you multiply 3 by 7 to get 21. Just remember to multiply or divide the two numbers (numerator and denominator) by the same number to get an equivalent fraction.
