Question 620685
Hi, there--
.
STEP I: Define a variable.
Let t be the amount of total sales for the week.
.
STEP II: Use the information in the problem to write an equation modeling the situation.
In algebra, "1/8 are cash sales" can b written as (1/8)t. Since the cash sales were $2,200, we write
{{{(1/8)t=2200}}}
.
STEP III: Solve for t by multiplying both sides of the equation by 8 (the reciprocal of 1/8).
{{{t=2200*8}}}
{{{t=17600}}}
.
In the context of this problem, t=17,600 means that the total of all sales is $17,600.
.
Hope tis helps. Feel free to email me if you still have questions about this.
