Step-by-step explanation:

$Ben\ invited\ p\ peoples\\\\$

Charges of birthday party:

$Flat\ fees=\$ 45\\\\Per\ person\ charges=\$ 5.50\\\\Charges\ for\ p\ people=p\times per\ person\ charges\\\\Charges\ for\ p\ people=p\times 5.50\\\\Charges\ for\ p\ people=5.50p\\\\Total\ charges\ for\ party=flat\ fee+charges\ for\ p\ person\\\\Total\ charges\ for\ party=45+5.50p$

Volunteers for a political campaign gave out 21/38 of their fliers. They gave out the remaining 612 fliers in another neighborho

dmitriy555 [2]

The volunteers gave 1368 fliers in total.

Step-by-step explanation:

Given,

Fliers given by volunteers in first neighborhood = $\frac{21}{38}$

Remaining fliers = 612

Fraction of remaining fliers = $1-\frac{21}{38}=\frac{38-21}{38}$

Fraction of remaining fliers = $\frac{17}{38}$

Let,

x be the total fliers given by volunteers.

$\frac{17}{38}\ of\ x=612$

$\frac{17}{38}x=612$

Multiplying both sides by $\frac{38}{17}$

$\frac{38}{17}*\frac{17}{38}x=612*\frac{38}{17}\\\\x=\frac{23256}{17}\\\\x=1368$

The volunteers gave 1368 fliers in total.
