2) Jonas is saving money to purchase a new motorbike that cost $6750. He currently has saved
$650. Jonas plans to earn money by mowing lawns. He will charge $40 per lawn.
A) Write and solve an inequality to determine the least amount of lawns that Jonas will need to
mow in order to have enough money to purchase the motorhike

Step-by-step explanation:

x= number of lawns Jonas needs to mow

40x+650=6750

Now Solve!!!

First subtract 650 from both sides

40x=6100

Now divide by 40

x=152.5 lawns

Jonas can't mow 1/2 a lawn, so he would have to mow 153.

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
