How much do you save per class by taking the longer-term class: weight training, $230 for 18 weeks (54 classes) or $400 for 36 weeks (108 classes)? a less than $1 b less than $5 c less than $10 d more than $10

A less than $1

Step-by-step explanation:

First, you need to know the price of each class. For that, you need to divide the total per class.

Eighteen weeks:

Thirty-six weeks:

Now you do the substaction $4.26 - $3.70 = $0.56 and that's the difference in price of classes

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
