To find the cost, we substitute the values of p = 10 and n = 30 into the expression 1.25p + 2.50n:
1.25(10) + 2.50(30)
= 12.50 + 75
= 87.50
Therefore, the cost for Mr. Imani to purchase 10 packs of paper and 30 notebooks is $87.50.
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,

To find the volume, we substitute the values of s = 4 and h = 6 into the formula s^2h:
(4^2)(6)
= 16(6)
= 96
Therefore, the volume of the square prism with s = 4 and h = 6 is 96 cubic centimeters.
(4^2)(6)
= 16(6)
= 96
Therefore, the volume of the square prism with s = 4 and h = 6 is 96 cubic centimeters.
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

$3,700
To find the earnings, we substitute the value of t = 12 into the expression 2,500 + 100t:
2,500 + 100(12)
= 2,500 + 1,200
= 3,700
Therefore, Ms. Tanaka will earn $3,700 for selling 12 televisions this month.
2,500 + 100(12)
= 2,500 + 1,200
= 3,700
Therefore, Ms. Tanaka will earn $3,700 for selling 12 televisions this month.
Robert is preparing a poster-board presentation. He wants to make a decorative pattern with 10 squares to fill part of the poster. The area of the poster board is 720 square inches. To find how much space Robert will have left for his presentation if he uses squares with 7-inch sides, evaluate
720 − 10

.(1 point)
580 square inches
230 square inches
9,940 square inches
34,790 square inches
To find the space left for Robert's presentation, we need to calculate the area of 10 squares with 7-inch sides and subtract that from the total area of the poster board, which is 720 square inches.
The area of one square is given by s^2, where s represents the length of each side.
Area of one square = 7^2 = 49 square inches
Area of 10 squares = 10 * 49 = 490 square inches
Space left for Robert's presentation = 720 - 490 = 230 square inches
Therefore, Robert will have 230 square inches of space left for his presentation.
The area of one square is given by s^2, where s represents the length of each side.
Area of one square = 7^2 = 49 square inches
Area of 10 squares = 10 * 49 = 490 square inches
Space left for Robert's presentation = 720 - 490 = 230 square inches
Therefore, Robert will have 230 square inches of space left for his presentation.

To find the cost for the garden, we substitute the values of l = 5 and w = 2 into the expression 7(l + 2w):
7(5 + 2(2))
= 7(5 + 4)
= 7(9)
= 63
Therefore, the cost for a garden that has a length of 5 yards and a width of 2 yards is $63.
7(5 + 2(2))
= 7(5 + 4)
= 7(9)
= 63
Therefore, the cost for a garden that has a length of 5 yards and a width of 2 yards is $63.
