Try that see what you get I'm pretty sure that is how you do it and also this is probably like 6th grade stuff but I hope I helped so here goes step by step.
1: multiply 4 and 62.95 you multiply because it says 62.95 for each plant
2: then add 59.95 and the number that has been multiplied
3: you should get your answer which should be $311.75
