Mrs lindy is purchasing notebooks for her students. she spends $52 on n notebooks. each notebook costs $3.25.

If you're asking for how many notebooks she bought, the answer is 16.

Step-by-step explanation:

Mrs. Lindy spends a total of 52$. If n represents the number of notebooks and each notebook costs $3.25, your equation will be 3.25n= 52. To solve for n, you have to get rid of 3.25 from both sides. Since you're multiplying 3.25 to n, divide by 3.25 to both sides to cancel it out. 52 divided by 3.25 equals 16, so n = 16. This means that Mrs. Lindy bought 16 notebooks.

I hope this helps!

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
