P(f | weekend) = p(f & weekend)/p(weekend)
.. = 10%/25%
.. = 0.4 = 2/5
Answer:
$6.48
Step-by-step explanation:
Initially calculate the 10% discount on $1.60, which results in $1.44. Then multiply $1.44 by 4.5 to find the total, yielding $6.48.
Answer:
Step-by-step explanation:
Delivery charge = $7.50
Cost per pizza = $14
Budgeted total = $60
7.50 + 14p < 60
First, subtract 7.50 from both sides
14p < 60 - 7.50
14p < 52.50
Now divide both sides by 14
p < 52.50 / 14
p < 3.75
Each pizza consists of 8 slices
Therefore, the total number of slices she can buy = 3.75 × 8
= 30 slices
Answer: To eliminate the y terms and solve for x with minimum steps, we should multiply the first equation by 9 and the second equation by -4.
Step-by-step explanation:
Given: Equation (1) 5x − 4y = 28
Equation (2) 3x - 9y = 30
To eliminate the y-terms and determine x in the fewest operations, it requires us to multiply equation (1) by 9 and equation (2) by -4 to have
9(5x − 4y) =9 (28) ⇒ 45x - 36y = 252
-4(3x - 9y) = -4(30) ⇒ -12x + 36y = -120
By adding both equations together, the y-term is eliminated, leading to 45x - 12x = 132
⇒ 33x = 132 ⇒ x = 4.
