Question

For a field trip, the school bought 39 sandwiches for $4.35 each and 42 bags of chips for 15 cents each. How much did the school spend in all

Answer 1

Answer:

$264.95$264.95

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:

\begin{gathered}sandwiches=(47)(\$4.60)\\\\sandwiches=\$216.2\end{gathered}sandwiches=(47)($4.60)sandwiches=$216.2

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:

\begin{gathered}bag\ of\ chips=(39)(\$1.25)\\\\bag\ of\ chips=\$48.75\end{gathered}bag of chips=(39)($1.25)bag of chips=$48.75

Therefore, the total amount school spent was:

\begin{gathered}Total\ spent=\$216.2+\$48.75\\\\Total\ spent=\$264.95\end{gathered}Total spent=$216.2+$48.75Total spent=$264.95
