Which is a better buy? 3 candy bars for $0.30 each or 3 candy bars for $1.50?

3 candy bars for $0.30 each is the better buy

Step-by-step explanation:

We must do the math to find out how much 3 candy bars will cost for 30 cents each.

0.30 x 3 = 0.90

Therefore, three candy bars cost 90 cents. 90 cents is less than a dollar and 50 cents. Therefore, the 3 candy bars for $0.30 each is the better deal.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

using pemdas, (order of operations) you'll see the answer is 24.
