Question

yoko just took a trip in her go-kart. the go-kart used 2.2 liters of fuel on the trip. now, the go-kart has 6.92 liters of fuel.
(a) let a be the amount of fuel the go-kart had before the trip (in liters). write an equation that can be used to find a. first choose an appropriate form. then fill in the blanks with the letter a and the numbers 2.2 and 6.92.
□+□=□
□-□=□
□×□=□
□÷□=□
(b) solve your equation for a to find the amount of fuel the go-kart had before the trip.
□ liters

Explanation:

Step1: Select equation form

The fuel before the trip minus used fuel equals remaining fuel, so choose the subtraction form: $\boldsymbol{A - 2.2 = 6.92}$

Step2: Isolate variable A

Add 2.2 to both sides to solve for A.
$A - 2.2 + 2.2 = 6.92 + 2.2$

Step3: Calculate final value

Compute the sum on the right-hand side.
$A = 6.92 + 2.2 = 9.12$

Answer:

(a) $\boldsymbol{A - 2.2 = 6.92}$
(b) $\boldsymbol{9.12}$ liters
