Answer:
There are 2 solutions:
X=-7.5
X=4.5
**The positive one is 4.5** so it should be that
Step-by-step explanation:
5x + 2 + 3x - 5 + x + 10 =
9x + 7
Number 15 is 80 i dont know about the others...sorry
A) that’s a $.30 decrease so to find the percent you do the formula
3.50x=.30
3.50x/3.50=.30/3.50
X=.0857
.0857=8.57% so$3.20 is 8.57% of $3.50
B) $3.20 markup=18.5% and $3.50 markup is 29.6% but this depends on where you round up at and you get the answer the same way, with the formula $2.70x=.80 because $3.50-$2.70 =.80
