Kelvin plans to buy potato chips and coke with $50. if he buys 3 packs of potato chips and 2 cans of coke, $9 will be left. if he buys 4 packs of potato chips and 5 cans of coke, he will need $21 more. find the prices of a pack of potato chips and a can of coke respectively.

Let the prices of a pack of potato chips and can of coke be x and y respectively
3x+2y=50-9
3x+2y=41 (1)
4x+5y=50+21
4x+5y=71(2)
Multiply (1) with 4 and (2) with3
12x+8y=164
12x+15y=213
On subtracting above eqs. we get
7y= 49
y=7
Putting value of y in (2)
4x+5(7)=71
4x+35=71
4x=36
x=9
x=$9
y=$7
MARK IT BRANLIEST PLZZZ

So the answer is 10.00 because the coke
