Rzqust [24]

Answer:

$3.97

Step-by-step explanation:

Three containers @$2.98 = 3 × 2.98 = $8.94

                                               Less $1 =   <u>-1.00 </u>

                                                                  7.94

Less 50% paid my mom = ½ × 7.94 =   <u>-3.97 </u>

                               Paid by Theresa =  $3.97

[(3 × 2.98) - 1] ÷ 2 = (8.94 - 1) ÷ 2 = 7.94 ÷ 2 = 3.97
