800-350=450
450/0.10=4500.
$4500

come on, this one should not even be injuring you, let alone killing
lets let s=weekly sales
that means that the variable "s" will stand for the amount of her weekly sales
now, we need the 10% of sales AND the $350 salary to equal $800
we write the equation
350+10%*s=800
350+.1s=800
.1s=450
s=4500
the answer is $4500 in weekly sales
if the algebra solving threw you, then you need to practice solving simple equations
350+.1s=800
subtract 350 from both sides and get
.1s=450
multiply both sides by 10
s=450
think about it, see how she had to earn 450 more to get 800 and she had to have sales of 10 times 450 so that 10% of sales would be 450
it makes sense
the algebra makes it more straightforward
math is cool
keep at it

Since she's already making $350 she has to make $450 in her weekly sales to get at least $800. If $450 is the 10% of the sales then she has to make $4500 in sales.

the sentence,"...a salesperson earns $350 per week plus 10% of her weekly sales..." can be written as:
Total Money Earned = $350 + (0.1)*(weekly sales)
we want the Total Money Earned to be AT LEST $800
so we have to write this as:
$800 ⤠$350 + (0.1)*(weekly sales)
(subtract $350 from both sides)
$800 -$350 ⤠(0.1)*(weekly sales)
$450 ⤠(0.1)*(weekly sales)
(divide both sides by 0.1)
$4,500 ⤠weekly sales
so we see that if the weekly sales are equal to $4,500 then the salesperson earns exactly $800, if the sales are more then $4,500, the salesperson will earn more then $800.
also, notice that it can be rather awkward to have to keep writing the words,"Total Money Earned" and "weekly sales", so instead we can write it as:
Total Money Earned = $350 + (0.1)*(weekly sales)
y = 350 +(0.1)x
where, y means Total Money Earned, and x means weekly sales

800 - 350 is 450
and if that's 10% of the total, then her sales must be 4,500 dollars to clear 800.

350+.10s=800
.10s=450
s=4500
she has to make $4500 in sales.
