To solve part a, do the following.
49.84-44.50=<span>5.34
5.34/44.50=x/100
after solving the proportion, x would be equal to 12.
To solve part b, do the following.
50+12=62
</span>To solve part c, do the following.
The amount of the tip is:
x/<span>57.50=62/100
which is </span><span>35.65
The total bill is:
35.65+</span>57.50=<span>93.15</span>
First you will add 4 to both sides the. you will combine the “ x” s since they are like terms, then you will divide the total x to both size to get it by itself :))
hope this helps !!!
Answer:
12 over 5, or 2.4
Step-by-step explanation:
I plugged it in my graphic calculator.
A. -17.1
the minus sign makes the first number a negative, and a negative plus a negative you add normally but put a negative sign in your answer
Answer:
$130
Step-by-step explanation:
Cost = 85
To make 30% profit, he would need to sell them at:
85 + (0.3)(85) = 110.5
Now, he would need to sell them at 110.5 AFTER giving a 15% discount. So essentially we are asking, "<em>What number discounted (decreased) by 15% would give us 110.5??"</em>
<em />
We can let that price be x and write the equation:
x - (0.15)(x) = 110.5
x - 0.15x = 110.5
0.85x = 110.5
x = 110.5/0.85 = 130
The retailer should mark the jacket at $130
