How does the method for solving equations with fractional or decimal coefficients and constants compare with the method for solving equations with integer coefficients and constants?

• The methods are essentially the same. There is no difference.

• The methods are essentially the same. The only extra step is that you begin solving by eliminating the fractions or the decimals from the equation.

• The methods are essentially the same. The only extra step is that you begin solving for the fractions or the decimals from the equation.

Janet wants to rent a U-Haul to move her mother. She spends $225 for the move. The U-Haul costs $45 up front and $1.50 a mile. What equation would you use to solve the number of miles her mother moved?

• 225 = 45x + 1.5

• 45 + 1.5x = 225

• 45x + 1.5x = 225

• 225 = 45(1.5) + 1.5x

A large pizza at Palanzio’s Pizzeria costs $6.80 plus $0.90 for each topping. The cost of a large cheese pizza at Guido’s Pizza is $7.30 plus $0.65 for each topping. Which system of equations could be used to find the number of toppings when both companies cost the same amount?

• y = 6.80 + .65x
  y=7.30+.90x

• x + y = 6.80
  x + y = 7.30

• y = 6.80+.90x
  y = 7.30 + .65x

• y + .90x = 6.80
  y + .65x = 7.30
