The system of equations that represent the cost of x shirts, and y pairs of pants are 4x + 3y = 85.50 and 3x + 5y = 115.00. Option (a) is correct.
A system of equations or an equation system is a collection of simultaneous equations.
Given that Shopping at Saver Mart, Lisa buys her children four shirts and three pairs of pants for $85.50 and She returns the next day and buys three shirts and five pairs of pants for $115.00
Now we have to find the system of equation
Lisa buys her children four shirts and three pairs of pants for $85.50 is given by
4x + 3y = 85.50
She buys three shirts and five pairs of pants for $115.00 is given by
3x + 5y = 115.00
Therefore the system of equations that represent the cost of x shirts, and y pairs of pants are
4x + 3y = 85.50 and 3x + 5y = 115.00
