Step-by-step explanation:
It is convenient to use a spreadsheet for this purpose.
The first row of numbers is constant at $45, as there is no daily charge associated with that payment method.
The second row of numbers uses the formula ...
cost = $12 + $4×(number of days)
The third row of numbers uses the formula ...
cost = $6×(number of days)
___
Of course, you can use these formulas to fill in the numbers by hand. For example, for 15 days, the charges are ...
- Early Pay: $45 (no calculation necessary)
- Deposit Plus: $12 + $4×15 = $12 +60 = $72
- Daily Pay: $6×15 = $90
Mr. Sanchez’s class sold 51 snickers and Mr. Kelly’s class sold 31 bottles of fruit juice.
Step-by-step explanation:
Step 1:
Assume x is the number of snickers sold and y is the number of fruit juices sold. It is given that both the classes sold 82 items in total. so
, take this as equation 1.
It is also given they both earned $115.56 out of which snickers sold for $1.50 each and fruit juice sold for $1.26 each. So,
, take this as equation 2.
Step 2:
Now we solve these equations.
Equation 1 can also be, , take this as equation 3.
Substitute equation 3 in 2,
Taking the known values to the right and keeping the unknown x values on the right, we get
Substitute this is equation 1,
So Mr. Sanchez’s class sold 51 snickers and Mr. Kelly’s class sold 31 bottles of fruit juice.
