Ron bought some toy cars at a garage sale. he gave 5 cars to his sister and had 2 cars left. which equation, when solved, will tell how many cars ron bought at the garage sale?

Alright, so let's call the number of cars he buys "x" So we know he gives 5 to his sister, so we have to subtract 5 from the total amount, then we know there is 2 left.

So

X-5=2

X=7

He bought 7 Cars.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
