Jalynn and emma enjoy hiking. jalynn hikes 1 mile in 20 minutes. emma hikes at a rate of 3 miles per hour. on sunday at 8: 00 a. m., they both left the trail head. the line representing jaylynn’s progress is graphed.

Which statements are true about the system that models this scenario?

The equations are equivalent so there are an infinite number of solutions.

Both lines will have a y-intercept of (0,0) since both hikers start at 8:00 a.m.

As shown on the graph, both lines have a slope of 1/20 because one must convert to the same units of time.

Step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
