PLEASE HELP! IM SO SLOW! I have two questions about this graph.

1. a computer program found that the line C=2t-89 is a good fit for the data. Please use this graph to predict how many cups of lemonade Lynn might sell on a day when the temperature is 74 degrees.

2. the high temperature this Sunday is expected to be 5 degrees warmer than the high temperature this Saturday. Using the line C=2t-89, how many more cups of lemonade should Lynn expect to sell on Sunday than Saturday.​

step-by-step explanation:

yes

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
