Answer:
.
Step-by-step explanation:
Total amount remaining = Initial amount in the card-( Cost per cup × (Number of cups) )
Each cup of coffee costs $1.50 and after buying 4 cups of coffee, the card had a $9 remaining balance.
i.e. 9 = Initial amount in card - (1.50 × 4)
⇒ 9 = Initial amount in card - (6)
⇒ Initial amount in card = 9+-6 =15
⇒ Initial amount in card = $15
Let A be the amount money remaining on the card after buying x cups of coffee.
So, A = 15 - 4x
Hence, the required equation is
.
There are total 17bills of $20 dollars and 6 for $10 bills.
We get the answer of $20 bills by dividing 340 and 20 then we get 17 then subtract the value from total bills than you get 6 bills for $10 dollars
The answer is B.
associative property, that means (_7.3 + 5.2) + 11 = _7.3 + ( 5.2 + 11) (algebra lesson)
-4.5 rose 9.7 then fell 4.8
-4.5 + 9.7 = 5.2
5.2 - 4.8 = 0.4
