Please help will mark brainliest!! The graph shows the total cost of a zoo membership for family. which equation can be used to find the total cost y for any number of family members X?
A. y= 10x
B. y= 25x
C. y= 10x +25
D. y= 25x +10

the answer is c

Step-by-step explanation:

cause math

Answer is C. y = 10x + 25

Step-by-step explanation:

This equation is in the form y = mx + b

we all know b is the y-intercept (where the line passes y axis)

When we look at the graph, we see that the line passes through y-axis at 25 which means our b is 25.

If we plug 25 in place of b in y = mx + b, C is the only option that makes sense

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
