Explanation:

1a

Step1: Find cost per lb

First, find the cost per pound of onions. The cost of 19 lbs is $57, so the cost per lb is $\frac{57}{19} = 3$ dollars per lb.

Step2: Calculate cost for 29 lbs

Now, to find the cost of 29 lbs, multiply the cost per lb by 29. So, $3\times29 = 87$ dollars.

Step1: Find cost per lb

First, find the cost per pound of potatoes. The cost of 12 lbs is $144, so the cost per lb is $\frac{144}{12}=12$ dollars per lb.

Step2: Calculate lbs for $504$

Now, to find how many lbs we can get with $504$, divide $504$ by the cost per lb. So, $\frac{504}{12} = 42$ lbs.

Step1: Find cost per lb

First, find the cost per pound of apples. The cost of 47 lbs is $188, so the cost per lb is $\frac{188}{47} = 4$ dollars per lb.

Step2: Calculate cost for 28 lbs

Now, to find the cost of 28 lbs, multiply the cost per lb by 28. So, $4\times28=112$ dollars.

$87$
