Lilian purchased a violin from Smash Music Stores. It regularly sold for $670, but was on sale at 10% off. She also had to pay 8% sales tax. She bought it on an installment plan and paid 15% of the total cost with tax as down payment. Her monthly payments were $58 per month for 1 year. a. What is the discount?
b. What is the sale price?
c. What is the sales tax?
d. What is the total cost of the violin?
e. What is the down payment?
f. What is the total she paid for the violin on the installment plan?
g. What is the finance charge

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option

step-by-step explanation: w

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
