Step-by-step explanation:
Most of them are +10 because for example 8+10 is 18
Answer:
Let's denote:
Number or gifts cost 20 = x
Number or gifts cost 22.5 = y
Then, we have:
x + y = 10
20x + 22.5y = 217.5
=> 20(10 - y) + 22.5y = 217.5
=> 2.5y = 17.5
=> y = 7 (Number or gifts cost 22.5)
=> x = 10 - 7 = 3 (Number or gifts cost 20)
Hope this helps!
