Please help. Full explanation if you can.1. The ratio of boots to sandals in a shoe store is 8:3. If there are 245 more boots than sandals in the store, how many boots are there??

Answers

392 boots. If you divide everything into "sets" of an unknown amount, there are 5 more "sets" of boots than sandals, also known as the 245 boots. So if you divide 245 by 5, you'll get the number of items in a "set". Then just multiply by 8 from the 8:3 ratio. If you check it, it will come out to 392 boots to 147 sandals, which I think is ridiculous since sandals are supposed to come in pairs so you should never have a odd number. But anyway, 392 - 147 = 245

If i buy 4 cans of soup for $6.00 which proportion can be used to find the cost of 13 cans

Answers

Final answer:

The cost of 13 cans of soup, given that 4 cans cost $6.00, can be determined using a proportion. The proportion is set up as 4 cans / $6.00 = 13 cans / x, which Solving for x indicates that the cost for 13 cans of soup is $19.50.

Explanation:

The question is asking for the cost of 13 cans of soup, given that 4 cans cost $6.00. This can be solved using a proportion. A proportion is set up as an equivalent fraction equation, where the ratio of the number of cans to the cost is equal in both situations. Here, the proportion is 4 cans / $6.00 = 13 cans / x, where x is the cost we are trying to find for 13 cans of soup.

To solve for x, we would use cross-multiply. This gives us 4x = 78, where we then divide both sides by 4 to get x = $19.50. So, the cost of 13 cans of soup is $19.50.
