mestny [16]

ANSWER

238\text{ fruit snacks per after-school program}

EXPLANATION

We have that there are 12 after school programmes and each one got an equal number of packages.

To find the number of fruit snacks that each received, we have to find the total number of fruit snacks.

The total number of fruit snacks can be found by multiplying the number of boxes of each flavor by the number of packages in each box, then adding them up:

\begin{gathered} \text{TOTAL}=(48\cdot4)+(78\cdot9)+(90\cdot11)+(108\cdot9) \\ \text{TOTAL}=192+702+990+972 \\ \text{TOTAL}=2856\text{ fruit snacks} \end{gathered}

Now, to <em>find the number of fruit snacks that each received</em>, divide by 12:

\begin{gathered} \frac{2856}{12} \\ 238\text{ fruit snacks per after-school program} \end{gathered}

Barbara can pay either $80 per month or one lump sum of $800 per year for car insurance. How much does she save yearly if she ch
Schach [20]

Answer:

$160

Step-by-step explanation:

In the monthly payment option she would pay $80 per month, therefore in a year (12 months) she would pay:

$80*12 =  $960

We can see that this amount is greater than the $800 she would pay in the lump sum payment option.

The money she would save is:

$960 - $800 = $160

She would save<u> $160 yearly</u> with the lump sum payment option.
