PSLEIan and Elijah shared the total cost of a gift. Ian paid $21 less than
25 of the cost of the gift. Elijah paid $30. How much did the gift cost?
Ian |
Elijah |
Total |
2 u - 21 |
3 u + 21 = 30 |
5 u |
Total amount paid = 5 u
Amount that Ian paid = 2 u - 21
Amount that Elijah paid = 3 u + 21 = 30
3 u = 30 - 21 = 9
1 u = 9 ÷ 3 = 3
Cost of the gift
= 5 u
= 5 x 3
= $15
Answer(s): $15
