She is correct because
She has 32p from the start.
Then she made 7 lots of ten (10 p) from her birthday
7×10=70
Add 70 pence +32p

So she got more.
The numbers that could have 4 tens are 40, 45 and 48.
The numbers that could not have four tens are 6, 13 and 30 because they do not have four tens. 6 has 0 tens, 13 has 1 ten and 30 has 3 tens.
