Answer:
$1.50
Step-by-step explanation:
To find the best deal, we first want to consider price per unit. To find the price per unit, we divide the price by the number of units. For the 10 shin guard package, our price is 14.50, and we divide that by 10 to get 1.45 . Therefore, our unit price for the package of 10 is $1.45 per shin guard. Similarly, we can find the unit price for the package of 15 to be 22.5/15 = $1.50 per shin guard. As 1.50 is greater than 1.45, the lowest unit price is for the package of 10.
The question is asking for us to compare the prices if we bought 30 of each. For the package of 10, we get 1.45*30 (as we're buying 30 for 1.45) = 43.5 as the total price, and for the package of 15, we get 1.5*30 = 45 as our price. As 15 and 10 are both factors of 30, we don't need to worry about converting it back into packages of 10/15. The difference between buying 30 at the lowest and highest unit price is therefore (45-43.5)=1.5 dollars
Answer:
$2,499.90
Step-by-step explanation:
So what the question is asking is for you to add/or subtract the payment deductions and deposits from your starting balance. A deposit is when cash or money is transferred or put into an checking account and a transaction is when you use your credit or debt card to pay for something. So Nick's starting balance(shown in the top right corner of the box)is $3,672.27. The last column to the right will be where you input Nick's account balance after each transaction or deposit. His first transaction is a payment to an auto repair shop ($1,721). Subtract $1,721 from $3,627.27 and Nicks Balance for 5/5 is $1,951.27(Put that on the first empty space in the last column on the left. On 5/7, Nick makes another payment for a purchase at a music shop($32.50). Subtract the $32.50 from the previous balance of $1,951.27 and Nicks new balance is $1,918.77. Then he makes a deposit on 5/9 into his account, so you ADD the $821.53 to the previous balance of $1,918.77 to get a new balance of $2,740.3. On 5/10 he pays his phone bill and so you subtract$101.50 from $2740.3 to get a new balance of $2,638.8. He made a second payment to Star Cable, which is the balance that they want to know, so you subtract $138.90 from $2,638.8 to get your final answer of $2,499.9
