A family eats dinner and the cost of the meal totals $50, before tax. The tax rate is 10% They also want to tip 20% of the bill, including tax. How much do they pay in all? $65.00 $88.00 $66.00 $55.00

66.00

Step-by-step explanation:

Convert 10% to a decimal by moving the point from 10. to 0.10 (back two places) and multiply it by 50 which gives you $5, which equals the tax they payed. Now they want to tip 20% of the entire bill including tax, so convert 20% to a decimal 20. to 0.20. Now multiply .20 * 55(55 is the $50 payed in meals and the $5 payed in taxes added) And you get $11 for the tip. Add 55 +11 and there's your answer

$65.00

Step-by-step explanation:

10% of 50$ is 5 and 20% of 50$ is 10

total: 50$

tax: 5$

tip: 10$

50 + 5 + 10 = 65

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
