3. The amount of money a family spends in Florida per week on groceries is normally distributed with a mean of $300 and a standard deviation of 543. Find the following population percentages using v score,
A. Less than $290,
B. More than $300,
C. Between $260 and $360,

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
