If you want to answer this, then you’ll first have to figure out how much money the one plate costs. So you would divide $23.88 by 4 and the number you get is how much they paid for one plate.
Next you would have to take the number you get from the division problem and multiply that by 10. That will give you your answer for how much she will need to pay.
Work:
$23.88 / 4 = 5.97
5.97 x 10 = 59.70
She needs to pay $59.70 for the plates.
