1/4=4/16 so the can has 3 servings and a some leftovers that are smaller than a serving. I think the answer is 3.
Rule: If x-k is a factor of p(x), then p(k) = 0. This is a special case of the remainder theorem.
Using that rule, we can see that x+5 is really x-(-5) so k = -5.
Therefore,
p(k) = 0
p(-5) = 0
so the answer is choice D.
195 ÷ 4 = 48.75
Is this what you wanted?
If you would like to know which one of the options is better to buy, you can calculate this using the following steps:
3 sandwiches ... $4.95
1 sandwich ... $x = ?
______________________
3 * x = 1 * 4.95 /3
x = 4.95 / 3 = $1.65
4 sandwiches ... $6.72
1 sandwich ... $y = ?
______________________
4 * y = 1 * 6.72 /4
y = 6.72 / 4 = $1.68
Result: You should buy sandwiches from the first option ($1.65 < $1.68 per unit).
Answer:
141,243
Step-by-step explanation:
1. Use PEMDAS
(300)(470) - 78 + 344 - 23 (Do muti first)
141,000 - 78 + 344 - 23 (You can do any order now)
