Based on the solution to an equation, Sam has a total spending money of $6,520.
An equation describes a mathematical statement of the equality or equivalence of two mathematical expressions, using the equals sign (=).
Sam's weekly savings = $570
The number of weeks of saving = 16
Total savings = $9,120 ($570 x 16)
Initial savings = $900
Additional savings = $9,120
Total amount saved = $10,020 ($900 + $9,120)
Let spending money = x
The ticket price = $1,500
10,020 = x + 7/3 x 1,500
10,020 = x + 3,500
x = 6,520 (10,020 - 3,500)
Thus, we can conclude that Sam's total spending money is $6,520.
Complete Question:
b) Sam is saving up money to buy plane tickets for a holiday after the semester. Every week, [2] Sam saves all of her income that she has not spent. Sam's weekly income is $570, so how much does she save at the end of 16 weeks, in dollars?
c) Sam had started with $900. Added to her 16 weeks of savings, the total comes to 7/3 of the ticket price, and the rest is spending money. How much spending money does Sam have?
