Answer:
ratio: $140/(7 calculators)
unit rate: $20/calculator
Step-by-step explanation:
For rates involving prices, we're usually interested in the price per item, so we divide the cost by the number of items to form the appropriate rate. Simplified, it is the unit rate.
ratio = $140/(7 calculators) = $20/calculator = unit rate
___
A "unit rate" is a rate with 1 (unit) in the denominator.
"per" can usually be considered to mean "divided by" in this context. As in "price per item" means "price divided by items".

It's noon now, which means that the current time is 12.00
75 x = 120 >> x is the amount of hours needed to get into 120 miles
x = 120 /75
= 1.6 hours
1.6 hours = 1 hour 36 minutes
12.00 + 1 hour 36 minutes = B. 1:36 PM

Answer:
here I'm confused that whether the selling price is Rs.9,200 or Rs.9.200
any ways you can take the help of below procedure
Step-by-step explanation:
here,
let marked price be X
discount(d)=20%
VAT=15%
SP with VAT= 9200
now,
SP without VAT= SP - VAT of SP
= 9200-15/100 ×9200
= 9200- 1380
=Rs. 1380
again,
SP= MP - D of MP
or,7820= x- 20/100 × x
or, 7820× 100 = 100x- 20x
or,782000=80x
or, 782000/80=X
or, X= 9775.
hence MP is Rs 9775
