Answer:

238 computers sold

Step-by-step explanation:

To solve for percent you move the percentage number (70) to behind the decimal so 70% would become .70 and now all you have to do is multiply that by the number you solving the percent for (340) so .70 * 340 = 238.

statuscvo [17]

Answer:

2/91.

Step-by-step explanation:

There are 15 marbles in the bag.

Prob(First draw is red) = 5/15 = 1/3.

Prob(Second draw is red) = 4/14 = 2/7.

Prob(Third draw is red) = 3/13.

So probability that all 3 are red = .1/3 * 2/7 * 3/13

= 6/273

= 2/91.

7. Saturday night, Larry is attending the concert of his favorite rock band. Tickets were $250 plus 6% tax. Parking is $20 for t
ElenaW [278]

Answer:

$347.45

Step-by-step explanation:

total = tickets + parking + t shirt + meal

tickets = 250 + 6% tax

6% tax is of 250, so this is equal to

250 + 6% of 250

6% = 0.06 because we divide by 100 to convert to a decimal from a percentage

thus, tickets = 250 + 0.06 of 250 = 250 * 1 + 0.06 * 250 + 1.06 * 250 = 265

parking = 20

use a similar strategy from the tickets and apply that to the t shirt

t shirt = 35 + 7 % tax = 35 + 0.07 * 35 = 1.07 * 35 = 37.45

meal = 25

total = 265 + 20 + 37.45 + 25 = $347.45
