At Frugal Foods a loaf of bread cost about $1 in 1980. In 2013, the loaf of bread cost $2.50.

1.A ratio is a comparison of two amounts by division. What is the ratio of the cost of a loaf of bread in 2013 to the cost in 1980? *$2.50/1

2.Assuming the price of clothing increased at the same rate, if the cost of jeans at Cobb’s Corner was $15 in 1980, what would the cost of the jeans be in 2013?
Explain. i don't get how to do this one

We can use a proportion. Cross multiply and solve for c.

2.5/1 = c/15

c = 37.50

It can't be $3.75 because the cost is much more in 2013 than it was in 1980.

1. The ratio of the cost of a loaf of bread in 2013 to the cost in 1980 is $2.50/$1, which is simplified to 2.5:1. So, the ratio is 2.5:1.

2. If the cost of jeans at Cobb's Corner was $15 in 1980 and assuming the price of clothing increased at the same rate, we can use the ratio we found in the previous question to find the cost of jeans in 2013.

Since the ratio of the cost of a loaf of bread in 2013 to the cost in 1980 was 2.5:1, we can apply that ratio to the cost of jeans.

$15 multiplied by 2.5 gives us $37.50. Therefore, the cost of the jeans in 2013 would be $37.50 in Cobb's Corner.

Remember, this is assuming that the price of jeans increased at the same rate as the cost of bread.

To find the cost of jeans in 2013, you can use the ratio you calculated in question 1. The ratio is $2.50/1, which means that the cost of bread increased by a factor of 2.5 from 1980 to 2013.

To apply this ratio to the cost of jeans in 1980, you need to multiply the cost of jeans in 1980 by the ratio.

Cost of jeans in 2013 = Cost of jeans in 1980 * Ratio

Substituting the given values, we have:

Cost of jeans in 2013 = $15 * 2.5 = $37.50

Therefore, the cost of jeans at Cobb's Corner in 2013 would be $37.50.

is it $3.75 because the unit rate is $2.50/1 and to get 10 you multiply the denominator, 1, by 15 and what u do to the bottom you do to the other so $2.50*15=37.5 and it equals 37.5/10 which is 3.75
