whats the unit rate:

882 yd in 9 secs

A grocery store sells four different jars of peanut butter. Determine which is the best buy, based on the cost per unit.
14 ounces for $1.44 20 ounces for $1.88
30 ounces for $3.48 38 ounces for $4.10

The unit rate for the first one is 98 yd/sec.

30 ounces for $3.48 is S8.62/oz. It is the best buy.

To find the unit rate, you need to divide the quantity by the amount of time. In this case, you are given the quantity of 882 yards and the time of 9 seconds.

To find the unit rate of yards per second, divide 882 by 9:

unit rate = 882 yd / 9 sec = 98 yd/sec

So, the unit rate of 882 yards in 9 seconds is 98 yards per second.

Now, let's determine the best buy among the four different jars of peanut butter based on the cost per unit. To do this, we need to calculate the cost per unit for each jar.

For the first jar:
Cost per unit = Cost / Quantity = $1.44 / 14 ounces = $0.103 per ounce

For the second jar:
Cost per unit = Cost / Quantity = $1.88 / 20 ounces = $0.094 per ounce

For the third jar:
Cost per unit = Cost / Quantity = $3.48 / 30 ounces = $0.116 per ounce

For the fourth jar:
Cost per unit = Cost / Quantity = $4.10 / 38 ounces = $0.108 per ounce

By comparing the cost per unit for each jar, we can see that the second jar, which costs $1.88 for 20 ounces, has the lowest cost per unit, $0.094 per ounce. Therefore, the second jar is the best buy based on the cost per unit.
