Alonso brings \$21$21dollar sign, 21 to the market to buy eggs and avocados. He gets eggs that cost \$2.50$2.50dollar sign, 2, point, 50. Then, he notices that the store only sells avocados in bags of 333 for \$5$5dollar sign, 5. He wants to buy as many avocados as he can with his remaining money. Let BBB represent the number of bags of avocados that Alonso buys. 1) Which inequality describes this scenario?
Answers
This scenario is described by the following inequality:
[tex]2.5 + 5B \leq 21[/tex]
-------------------------
First, we find Alonso's total spendings.He spends $2.50 in eggs.After that, he buys B bags of avocados, each costing $5, and thus, his spending on avocados is: [tex]5B[/tex]His total spending is given by:[tex]T = 2.5 + 5B[/tex]
-------------------------
He brought $21 to the market, thus, his total spending can be at most $21, that is:[tex]T \leq 21[/tex]
Replacing the equation for T, the inequality is:
[tex]2.5 + 5B \leq 21[/tex]

#15
Answers
Step-by-step explanation:
82 + 76 + 42 = 200
42 out of 200 hmmm
200 / 2 = 100
42 / 2 = 21
21 out of 100 = 42 out of 200
=
21%
then you set up a proportion: %/100 = part/whole (and whichever thing you’re trying to solve for will be x)
so for this problem: x/100 = 42/200 (x is what you’re solving for: you’re trying to find the percent of people that prefer strawberry ice cream out of the 200 people surveyed)
then: cross multiply
i like to start with the x first so:
200 • x = 200x
and
42 • 100 = 4200
then finally put these together to make an algebraic equation: 200x = 4200
solve from there:
4200 divided by 200 (because you want x by itself) is 21 so you’re left with:
x = 21
now remember how we used x to represent the percent out of 100 on our proportion? this means that 21% of people (out of the 200) prefer strawberry ice cream
hope this helps!
