Question

4 mugs and 3 bowls cost $24.50. 2 mugs and 4 bowls cost $18.50. How much does a bowl cost?

Answer 1

$2.50

Explanation:

to solve this equation you should start with let statements

let m = mugs

let b = bowls

then set the equations up like this

4m + 3b = 24.5

2m + 4b = 18.5

you can multiply the second equation by 2

then youll be able to use elimination to solve the equation

4m + 3b = 24.5

4m + 8b = 37

subtract them

-5b = -12.5

b is 2.5

this means that a bowl costs $2.50
