As the student council treasurer, you prepare the budget for your class rafting trip. Each large raft
costs $110 to rent and each small raft costs $70 to rent. You have $1,600 to spend. Write a
linear equation for this situation

answer: 457.14

step-by-step explanation:

205 - 45 = 160

160 / .35 = 457.142857

the answer is c)8

step-by-step explanaction:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
