Please help me with this question thank you

Answer 1

B) Let x = amount paid to cashier

x - $31 = $69

x = $100

Explanation:

We want to determine the amount Lemon paid the cashier. Therefore, the unknown variable is:

• Let x = the amount he paid the cashier.

If Lemon received $31 in change, then the amount he paid the cashier less the change is equal to the cost of the walnuts:

• x - $31 = $69

To solve the equation, add $31 to both sides:

• x - $31 + $31 = $69 + $31
• x = $100

Therefore, the amount Lemon paid the cashier was $100.

Answer 2

2): x - $31 = $69

Explanation:

See attached worksheet. The derivation of the answer, x - $69 = $31 (then x = $100) is shown. Convert the written question into an equation: If x is the amount given the cashier, then once $69 is subracted, Lemon receives $31:

x - $69 = $31

This can be rearranged to: x - $31 = $69, the second answer option. Other options have errors, noted by the red circles. There are no reasons that inequalities are involved, and seemingly random values of $61 and $30 have no relationship to the problem.
