If you buy 5 yards of cotton cloth at $7 a yard, 2 yards of silk cloth as $5.25 a yard, and 12 shirts at $14 a piece, and you pay the clerk $220 in cash, what would you expect in change?

Amount of change he will get is $6.50 .

Step-by-step explanation:

We have , If you buy 5 yards of cotton cloth at $7 a yard, 2 yards of silk cloth as $5.25 a yard, and 12 shirts at $14 a piece, and you pay the clerk $220 in cash, We need to find what would you expect in change . Let's find out:

Total amount of change = $220 - (Amount of products taken)

⇒

⇒

⇒ $

Therefore , Amount of change he will get is $6.50 .

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
