Lenora buys 3.7 pounds of potatoes that cost $0.29 per pound and 4.8 pounds of onions that cost $1.23 per pound. How much does L
Likurg_2 [28]

Given:

Cost per pound of potatoes is $0.29.

Cost per pound of onions is $1.23.

To Find:

The total amount Lenora spent on potatoes and onions.

Answer:

<h2>Lenora pays 6 dollars and about 98 cents in all.</h2>

Step-by-step explanation:

The per pound price of potatoes is $0.29.

Lenora buys 3.7 pounds of potatoes.

To calculate the cost of the potatoes she bought, we must multiply the per pound rate with the total weight of potatoes she bought.

So, the cost of Lenora's potatoes is $(0.29)(3.7) = $1.073

Next, the per pound rate of onions is $1.23.

Lenora buys 4.8 pounds of onions.

To calculate the cost of the onions she bought, we must multiply the per pound rate with the total weight of onions she bought.

So, the cost of Lenora's onions is $(1.23)(4.8) = $5.904

To find the toal cost, we add the price she paid for the potatoes and onions which is $1.073 + $5.904 = $6.977.

<h2>This means Lenora pays 6 dollars and about 98 cents in all.</h2>

How much water should be added to 6 gallons of pure acid in order to obtain the 24% acid solution?
Helen [10]

Answer:

19 gallons

Step-by-step explanation:

Let x gallons be the amount of water which should be added to 6 gallons of pure acid in order to obtain the 24% acid solution.

Amount of water = x gallons

Amount of pure acid = 6 gallons

Amount of acid solution = x + 6 gallons

Amount of acid in acid solution = 24%

So, there are 0.24(x+6) gallons of acid in acid solution.

Hence,

0.24(x+6)=6

Solve this equation. Multiply it by 100:

24(x+6)=600\\ \\24x+144=600\\ \\24x=600-144\\ \\24x=456\\ \\x=19\ gallons
