Mr. Imani wants to purchase paper and notebooks for his classroom. At Dollar Discount he can buy packs of paper, p, for $1.25 each and notebooks, n, for $2.50 each. This is modeled by 1.25p + 2.50n Evaluate for p = 10 and n = 30 to find how much it will cost Mr Imani to purchase 10 packs of paper and 30 notebooks.

Answer 1

To evaluate the expression 1.25p + 2.50n for p = 10 and n = 30, substitute the values into the expression:

1.25(10) + 2.50(30)

= 12.5 + 75

= 87.5

Therefore, it will cost Mr. Imani $87.50 to purchase 10 packs of paper and 30 notebooks.

Answer 2

The formula for finding the volume of a square prism is s2h, where s is the length of each side of the square base and h is the height of the prism. Evaluate to find the volume given values of s = 4 and h = 6

Answer 3

To evaluate the expression s^2h for s = 4 and h = 6, substitute the values into the expression:

4^2 * 6

= 16 * 6

= 96

Therefore, the volume of the square prism is 96.

Answer 4

Each month Ms. Tanaka is paid a base salary of $2,500 in addition to $100 for each television that she sells. This is modeled by 2,500 + 100t, where t represents the number of televisions. Evaluate for t = 12 to find how much Ms. Tanaka will earn for selling 12 televisions this month.

Answer 5

To evaluate the expression 2,500 + 100t for t = 12, substitute the value into the expression:

2,500 + 100(12)

= 2,500 + 1,200

= 3,700

Therefore, Ms. Tanaka will earn $3,700 for selling 12 televisions this month.
