Answer:
$22.50
Step-by-step explanation:
50/100 = x/45
cross multiply
50 × 45 = 100 × x
2250 = 100x
divide both sides by 100
22.5 = x
*note: marksup the price means that $45 should be more than what the value of x is. $45 is more than $22.50. you can also check your work by looking at the fact $22.50 is exactly half (50%) the amount of $45*
