Step-by-step explanation:
Your question isn't complete. First and foremost, to be able to solve this, we need to know the total marks of the examination.
Let's assume that the total marks for the exam is 80. Since Donte scored 55 on his mastery exam, the percent that he score will be:
= 55/80 × 100
= 68.75%
20%=0.2
14*0.2 = 2.8 ( $2.80 is the tip she will be giving her)
$14+$2.80 = $16.80 ( what she will be giving in total)
$20-$16.80 = $3.20 (the change she will get back)
The answer is no solutions
