The given inequality is 2.5x + 4y ≤ 60. x is the bags of chips and y is the jars of salsa,
Replace x and y in the equation with the possible answers and solve:
A) 10 chips and 2 salsas:
2.5(10) +4(2) = 25 + 8 = 32 This is less than 60 so is a solution.
B) 20 chips, 2 salsas:
2.5(20) + 4(2) = 50 + 8 = 58, this is less than 60 so is a solution.
C) 14 chips, 5 salsas:
2.5(14) + 4(5) = 35 + 20 = 55, this is less than 60 so is a solution.
D) 18 chips , 6 salsas:
2.5(18) + 4(6) = 45 + 24 = 69, this is greater than 60 so is not a solution.
18 bags of chips and 6 jars of salsa is not a solution.
Anita's account had linear growth
Miguel's account had exponential growth.
Miguel's account grew faster because exponential growth is faster than linear growth
The rate to convert yards to meters is
So, if you multiply both sides by 8, you get
To round the answer to the nearest tenth, we need to choose between 7.3 and 7.4. Since the hundreths digit is 1, which is less than 5, 7.3 is nearest to 7.3152 than 7.4, so the correct answer is 7.3
