A certain brand of coffee comes in two sizes. A 10.15-ounce package costs 2.98. A 27.8 -ounce package costs 8.99. Find the unit price for each size. Then state which size is the better buy based on the unit price. Round your answers to the nearest cent.

Size 2 with 3.1 units price

Step-by-step explanation:

Size 1:

A 10.15-ounce package costs 2.98.

Units price of size 1 = 10.15 / 2.98

= 3.4060

Approximately 3.4

Size 2:

A 27.8 -ounce package costs 8.99.

Units price of size 2 = 27.8 / 8.99

= 3.0923

Approximately 3.1

The best size which is better buy based on unit price is size 2 with 3.1 units price

step-by-step explanation:

you are throwing one dart

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
