Ответ:
Required system of equation is
4s+3c=26 and 5s+2c=29.
Step-by-step explanation:
Let cost of 1 sundaes = s
Let cost of 1 cone = c
Then statement "Marcus is treating his family to ice cream he buys 4 Sundaes and 3 cones for the total of $26", gives equation:
4s+3c=26...(i)
And statement "Brian also buy ice cream for his family his total is 29 for purchasing 2 cones and 5 Sundaes " gives equation:
5s+2c=29...(ii)
Hence required system of equation is
4s+3c=26 and 5s+2c=29.
