Lyla is shopping for school supplies. she has $20.00 to spend. she plans to buy a package of pens for $4.98. she also wants to buy a calculator. all calculators are being sold for 30 percent less than the original price. write an inequality that can be used to find the original price, x, of a calculator lyla can buy.
We know that Lyla has $20.00 to spend, which is the maximum money she can use. In other words, she cannot spend more than $20.00, it's $20.00 or lower, this means we have to use in the inequality, that's the restriction.
Now, we know that the package of pens is $4.98, and the calculators cost 30 percent less than the original price, that means they cost with discount included.
So, the inequality that models this situation is
Now, solve for
This means that Lyla can by a calculator which original price won't go higher than $21.46. She can effort calculators that costs $21.46 or lower.
i think its doubled. let me know
