Samantha Bell · Answer 1

If you put it in algebraic terms, and pizza is p, soda is s

1p + 1s = 1.99

3p + 2s = 5.48

to find the cost individually you use simultaneous equations

by multiplying the top equation by 2 you get

2p + 2s = 3.98

and then you can say that 1p is 5.48-3.98 = 1.50

and if 1p = 1.50, 1s = 1.99-1.50=49
