For a field trip, the school bought 47 sandwiches for $4.60 each and 39 bags of chips for $1.25 each. how much did the school spend in all?

Step-by-step explanation:

You know that 1 sandwich costs $4.60 and the school bought 47 sandwiches.

Therefore, in order to calculate the total cost of 47 sandwiches, you need  to multiply this number of sandwiches bought by the schoole, by the cost of 1 sandwich. Then:

You know that 1 bag of chip costs $1.25 and the school bought  39 bags of chips.

So, in order to calculate the total cost of  39 bags of chips, you must  multiply the total number of them bought by the school, by the cost of 1 bag of chips.

Then:

Therefore, the total amount school spent was:

Multiply the price per each by the quantity of each:

Sandwiches: 4.60 x 47 = $216.20

Chips: 1.25 x 39 = $48.75

Total spent = 216.20 + 48.75 = $264.95

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
