The regression equation y = 4x + 20 approximates the number of people attending a picnic, y,
given the number of flyers used to advertise it, x.
which statement is true?
o
for every extra flyer used in advertising, the attendance increases by 4 people.
o
for every extra flyer used in advertising, the attendance increases by 20 people.
for every extra person attending a picnic, the number of flyers used to advertise it
increases by 4.
for every extra person attending a picnic, the number of flyers used to advertise it
increases by 20.

where are the choices?

mordancy.

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
