Final answer:
Jayden needs to measure out 2 cups of sugar and only has a 1-cup scoop. He will need to fill the 1-cup scoop twice, which means Jayden needs 2 scoops of sugar.
Step-by-step explanation:
Jayden needs to measure out 2 cups of sugar using only a cup scoop. To solve this, it is very simple: since Jayden has a 1-cup scoop and he needs 2 cups of sugar, he will need to use the scoop twice. The reason is that 1 cup + 1 cup equals 2 cups, so the 1-cup scoop needs to be filled twice to measure out the needed 2 cups of sugar. Therefore, Jayden needs 2 scoops of sugar to measure out his 2 cups.
