im not quite sure on this one but i will do my best to help you. since maria saves 5 per week we multiply that by her earnings from her birthday. 5x50=250. we can also take the 7 dollars julyssa makes every week and multiply that with the product we got with maria. 250x7=1650. hence the answer to ur equation is 1650.
Step-by-step explanation:
if this is wrong i am very sorry i was only trying to help.
take algebra book. it can be placed first or 2nd or 3rd or 4th or last. so 5 different ways. but geometry book will be arranged in 4 ways, since algebra book is already arranged.
