I think it's :
Part A ; $30 * (x) + $13
$28 * (x) + $15
Part B ; so $30 * 4 + $13 = $133 vs.
$28 * 4 + $15 = $111 so that would mean company B Would charge the least amount.
Part C ; the difference between company a and company B prices is $22.
4/5=24/30 and 4/6=20/30
So three easy fractions between these are 21/30=7/10, 22/30=11/15 and 23/30.
