An grocery store sign indicates hat plums are 6 for 1.50, and a sign by the apples indicates that they are 5 for 3.00. Find the total cost of buying 2 plums and 2 apples and how to solve in ratios?
The total is $1.70
Ok so you would take the number 6 and divide that by 1.50 since there are 6 plumes for 1.50. That is 25 cents per plum. But you want to buy 2 plums so multiply 25 by 2 which is 50 cents. Do the same for the apples,divide 3.00 by 5 which is 60 cents per apple but you want two apples so that is 1.20 for both apples. Then you have to figure out the cost of the plums and the apples so you add 50 cents to 1.20 and you get 1.70.
To find the total cost of buying 2 plums and 2 apples, we need to calculate the cost of each fruit individually, then add them together.
First, let's find the cost of the plums. The sign indicates that plums are 6 for 1.50, which means you get 6 plums for $1.50. To calculate the cost of each plum, divide the total cost by the number of plums: 1.50 / 6 = $0.25 per plum.
Next, let's find the cost of the apples. The sign indicates that apples are 5 for $3.00, which means you get 5 apples for $3.00. To calculate the cost of each apple, divide the total cost by the number of apples: 3.00 / 5 = $0.60 per apple.
Now that we have the cost per plum and the cost per apple, we can calculate the total cost of buying 2 plums and 2 apples.
The cost of 2 plums is 2 * $0.25 = $0.50.
The cost of 2 apples is 2 * $0.60 = $1.20.
To find the total cost, we add up the cost of the plums and the apples: $0.50 + $1.20 = $1.70.
Therefore, the total cost of buying 2 plums and 2 apples is $1.70.
Now, let's discuss how to solve this problem using ratios.
Ratios involve comparing quantities using fractions or proportions. In this case, we can use the ratios of the quantities given by the signs to find the cost of each fruit.
The ratio for plums is 6:1.50, which can be simplified to 2:0.50 or 4:1.
This means that for every 4 plums, you pay $1. So the cost of 1 plum is $1/4 = $0.25.
The ratio for apples is 5:3.00, which can also be simplified to 1:0.60.
This means that for every 1 apple, you pay $0.60.
To find the total cost of 2 plums and 2 apples using ratios, we multiply the cost of each fruit by the number of fruits bought.
The cost of 2 plums is 2 * $0.25 = $0.50.
The cost of 2 apples is 2 * $0.60 = $1.20.
Adding up the cost of the plums and the apples, we get $0.50 + $1.20 = $1.70 as the total cost.
Therefore, the total cost of buying 2 plums and 2 apples is $1.70, and you can solve this problem using ratios by comparing the quantities and calculating the cost based on the given ratios.
