Question

PLEASE HEP ME




Mike's Bike Shop needs to purchase some supplies. He needs 5 tires which cost $5 each and several water bottle holders which cost $2 each. He does not want to spend more than $399 for the 5 tires and the bottle holders.

Which of the following inequalities could be used to solve for w, the number of water bottle holders he can order?

$7w < $399
$25 + $7w < $399
$25 + $2w < $399
$5 + w < $399

Answer 3

ok one sec

Answer 4

C or D

Answer 5

Well, the max amount of money that he can spend is $399. 5 tires is $25, and each bottle cost $2. $25 + $2w < $399 ^ the amount of bottles times 2, plus the 25 can't get pass 399. This inequality shows that. Got it?

Answer 6

D is wrong.

Answer 7

C <

Answer 8

the w implies that a bottle is only $1 and the 5 tires are just $5, that is not true.

Answer 14

i dont really know obviously

Answer 15

Well what you drew doesn't really help you.

Answer 16

^^ yea...

Answer 17

Main idea here is that the total $ he can spend is 399

Answer 18

That's automatically <399 for the 2nd part

Answer 19

he already has the info of 5 tires and $5 each. that's a fixed $25, no change for the tires or any variables

Answer 20

bottles are $2 each but he doesn't know how many so that's $2w

Answer 21

Put it all together and it's a straight foward 25+2w<399

Answer 22

More sense?

Answer 23

Answer 24
