Help please!!!!!!!!!!!!!!!!!!!!!!!!

I would say y = sin(x + 2).

Why?

1. Is it the sine function for sure.

Karolina [17]

We have been given that a retailer buys cases of 24 shirts for $30/case and then resells them in packs of 5 for $8/pack.

Further, we know that retailer sold all the shirts he purchased and profited $84 on the sale.

Let us first find LCM of 24 and 5. The LCM is 120.

Now, let us assume that the retailer bought 120x shirts. Therefore total profit will be:

$\text{Profit=}(24x)(8)-(5x)(30)\\\text{Profit=}192x-150x\\\text{Profit=}42x\\$

We can set this equal to the given profit to figure out the value of x first.

$42x=84\Rightarrow x=2$

Therefore, the retailer sold 120(2)=240 shirts, that is, 48 packs.
