Alex bought lemons that were priced at 2 lemons for 18¢. What was the total cost of 5 lemons?
x/5 = 18/2
2x = 90
x = 45
or
if 2 lemons cost 18 cents, then
1 lemon costs 9 cents, and
5 lemons cost 45 cents
To find the total cost of 5 lemons, we need to first find the cost of one lemon and then multiply that by 5.
Given that Alex bought 2 lemons for 18¢, we can divide the total cost by the number of lemons to find the cost of one lemon. So, 18¢ ÷ 2 lemons = 9¢ per lemon.
Now, we can find the total cost of 5 lemons by multiplying the cost of one lemon (9¢) by the total number of lemons (5). 5 lemons × 9¢ per lemon = 45¢.
Therefore, the total cost of 5 lemons is 45¢.
