Answer:
she at least has $203 to buy a pair of shoes.
Step-by-step explanation:
Total allowance for Christmas = $300
Cost of 1 hood = $52
Cost of 1 pair of pants = $45
Let the cost of a pair of shoes = $m
Now, Cost of 1 hoodie + 1 pants + 1 pair shoes = $300
or, $52 + $45 + m = $300
or, m = 300 - 97 = 203
or, m = $203
Hence, she at least has $203 to buy a pair of shoes.

It is easier to multiply. For example: 63 multiply by 7
63 x 7 = (60+3) x 7 = 60 x 7 + 3 x 7 = 420 + 21 = 441
Another example : 25 x 73
25 x 73 = (20+5) x (70+3) = 20 x 70 + 20x3 + 5x70 + 5x3
= 1400 + 60 + 350 + 15 = 1875
