Question

Question 3 (25 points) Shopping at Saver Mart, Lisa buys her children four shirts and three pairs of pants for $85.50. She returns the next day and buys three shirts and five pairs of pants for $115.00. Write a system of equations that represents the cost of x shirts, and y pairs of pants. Oa 4x+3y=85.50 3x+5y=115.00 Ob 4x+3y=115.00 3x+5y=85.50 Oc x+y=85.50 x+y=115.00 3x+4y=85.50 5x+3y=115.00

Answer 1

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
