If you want to the know the total price of the jeans, with discount coupon and sales tax then it's $15.76

$75 x 0.30 = $22.50

$22.50 - $10 = $12.50

$12.50 + $3.26 = $15.76

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

75.00- 17.34-10.00-3.26 - 30 percent.

The jean were 31.08 dollars

Step-by-step explanation:

75 - 10 = 65

3.26 - 65 = 61.74

61.74 - 17.34 = 44.40

30% of 44.40

= 31.08 dollars

So, she paid (75-17.34=57.66) for the purchase

Or, the jeans costed 57.66-3.26=54.4 (prize minus sales tax)

But she got a 10 dollars off! so that means that the jeans actually costed 64.4

now, the 64.40 was the prize discounted by 30%:

64.40=(100-30)%*x

where x was the original prize

64.40=0.7x

644=7x

x=644/7

x=92

so the original prize was 92 dollars.
