Step-by-step explanation:
this problem is similar to a scale drawing where we can set up a proportion:
'x' is to 5 as 162 is to 30
x/5 = 162/30
cross-multiply:
30x = 810
x = 810/30
x = 27

Answer:
$45.
Step-by-step explanation:
When the TV is bought on hire purchase, you deposit $35 and pay $30 monthly. There are 12 payments. 12 * 30 = $360. 360 + 35 = $395.
Since cash would've cost $350, the amount of money saved by paying cash is 395 - 350 = $45.
Hope this helps!
