Answer:
Julie can buy 4 plants
Step-by-step explanation:
A plant costs £6.80 and Julie has £30.
In order to find out how many plants she can buy with £30, we need to see how much times £6.80 can go into £30. In other words, we need to divide £30 by £6.80 so we get the number times it can go into £30. That will be the number of plants.
£30 ÷ £6.80 = 4.41176470588
Julie can't get 0.41176470588 of a plant so we have to round it to 4. She can buy 4 plants.
She has a bit of money left over (you can tell by the decimal number), but that isn't enough to buy another plant. So she buys 4 and has £2.80 left.
£6.80 x 4 = £27.20
