Ezra needs at least $37 to buy some books. She already has $25. Which graph best represents all the possible dollar amounts that Ezra can save to buy the books? Number line graph with open circle on 0 and 12 and shading in between. Number line graph with closed circles on 0 and 12 and shading in between. Number line graph with open circle on 12 and shading to the right. Number line graph with closed circle on 12 and shading to the right.

Number line graph with closed circle on 12 and shading to the right.

Explanation:

if you see Ezra needs $37 and if she has less than $12 then she will not have $37. she needs exactly $12 or more. The closed circle tells us that 12 is a answer and the shading to the right means more than 12.

he has now walked a total of what?

if i know what this is maybe i can

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
