so she has $550 and she did 20 cats and it costs $5 per cat and 5 x 20 is $100 and $550 - $100 = 450 and 450 divided by 10 ( because it's $10 per dog) is 45.
2 C 5 = 145 Its hard to type that but 2 would go over the 5 and an equals sign would be in the middle, then C over 45. To solve then take 145 times 2 and divide it by 5. Hope this helps.
If 2 eggs with bacon cost 2.70, and 1 egg with bacon costs 1.80, that means that 1 egg costs 0.90, so when we subtract once more 0.90 we get the price of the bacon alone, which is in this case 0.90.
