Jose wants to spend no more than $30 on apples and grapes for the month. Apples cost $1.50 per pound, and grapes cost $2 per pound. Jose also wants his monthly caloric intake from apples and grapes to be greater than 2000 calories. He determines that 1 pound of apples has 200 calories and 1 pound of grapes has 300 calories.
Let a represent the number of pounds of apples, and g represent the number of pounds of grapes. Which system of inequalities can be used to determine the number of pounds of apples and grapes that Jose can buy for a month?CED.3

• 1.5a + 2g >=30
  200a + 300g > 2000

• 1.5a + 2g <= 30
  200a + 300g > 2000

• 2a + 1.5g <= 30
  300a + 200g >2000

• 2a + 1.5g >= 30
  200a + 300g <2000

The first term in an arithmetic sequence is 5. The fourth term in the sequence is -4. The tenth term is -22

• f(n) = -n

• f(n) = n + 4

• f(n)= -3n + 8
