Final answer:
To find out how much Ms. Martin spent on kitchen equipment, we subtracted the combined remaining amount of money and Mr. Jones's expenses from the initial total savings and then subtracted Mr. Jones’s expenses from this total. Ms. Martin spent $33,980 on kitchen equipment.
Step-by-step explanation:
The question is asking us to determine how much money Ms. Martin spent on kitchen equipment, considering the total amount saved, the remainder after spending, and the overall leftovers once they both made their purchases.
Ms. Martin and Mr. Jones initially saved $56,480. After their purchases, they had $35,200 left. Mr. Jones spent $3,450 on tables and chairs. We know that Ms. Martin had $15,600 left after buying kitchen equipment. If we sum $15,600 (Ms. Martin's remaining money) and $3,450 (Mr. Jones's expense), we get $19,050. This amount represents Ms. Martin's remaining money plus Mr. Jones's spending, which, when subtracted from the initial total, will tell us how much was spent in all:
$56,480 (initial total) - $19,050 (remaining money and Mr. Jones's spending) = $37,430 (total spent by both Ms. Martin and Mr. Jones).
To find Ms. Martin's expenditure on kitchen equipment, we subtract the amount Mr. Jones spent from the total spent:
$37,430 (total spent) - $3,450 (Mr. Jones's spending) = $33,980 (Ms. Martin's spending on kitchen equipment).
