Answer:
$75.40
Step-by-step explanation:
first you need to find what 30% of 58 is. to find that you would multiply the decimal form of the percentage (so 30% would become 0.3) by 58. this gets you 17.4. then you add that to the original price (58) to get the answer (75.4). then of course you change the format so that it can fit the whole dollar and cent thing so you get $75.40.
hope this helped :))
