A customer spends $41.94 on 6 pairs of flip-flops. If each pair of flip-flops costs c dollars, which statement is true?

• The equation c+6=41.94 can represent the scenario, and each pair of flip-flops costs $35.94.

• The equation c+41.94=6 can represent the scenario, and each pair of flip-flops costs $35.94.

• The equation 6c=41.94 can represent the scenario, and each pair of flip-flips costs $6.99.

• The equation 41.94c=6 can represent the scenario, and each pair of flip-flops costs $6.99.
