Clare got $250 for her birthday. She purchases a pair of boots for $98, a sweater for $37 and a purse for $62. The sales tax rate is 7.5%. How much of her birthday money will she have left?

98+37+62= 197*0.075=14.775

197+14.775= 211.775

250- 211.775= 38.225

Clare has $38.23 left

(my steps went: add all the purchases together, then find the sales tax. add the purchase amount to the sales tax. Subtract that amount from the starting amount, to see how much she has left.

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
