$1.$All employees at Kranston Sports Inc. are paid based on an annual salary rather than an hourly wage. However, some employees are paid weekly, while others are paid every other week $($biweekly$).$ Employees paid weekly receive $52$ paychecks; employees paid biweekly receive $26$ paychecks. The algorithm shown in Figure $1-15$ should calculate and display the gross pay for each employee; however, some of the instructions are missing from the algorithm. Complete the algorithm. $2.$Create an algorithm that tells someone how to evaluate the following expression: $7*520/2+4*2.$ The $/$ operator means division, and the $*$ operator means multipli$-$cation. $($As you may remember from your math courses, division and multiplication are performed before addition and subtraction.$)3.$Store A is having a BoGoHo $($Buy One, Get One Half Off $)$ sale. Store B is not having a sale, but sometimes its prices are much lower than at Store A$.$ Write an algorithm that determines whether it$$s cheaper to buy two of the item at Store A or Store B$.$ The algo$-$rithm should display either the message $$Buy at store A$$ or the message $$Buy at store B$.$ If the prices would be the same at both stores, display the $$Buy at store A$$ message. $4.$The algorithm in Figure $1-16$ should get Robin the Robot seated in the chair, but it does not work correctly. Correct the algorithm. This is what the algorithm has:

$1.$ repeat $(3$ times$)$

walk forward one complete step

end repeat

$2.$ turn left $90$ degrees

$3.$ repeat $(2$ times$)$

walk forward one complete step

end repeat

$4.$ turn right $90$ degrees

$5.$ repeat $(2$ times$)$

walk forward one complete step

end repeat

$6.$ turn right $90$ degrees

$7.$ walk forward one complete step

$8.$ turn right $90$ degrees

$9.$ repeat $(4$ times$)$

walk forward one complete step

end repeat

$10.$ turn right $90$ degrees

$11.$ sit down
