The monthly cost of a short term disability insurance policy varies directly as the salary of the employee. Wanda has an annual salary of $37,500, and the monthly cost for her policy is $18.75. Randy has an annual salary of $47,000. What should Randy expect to pay for his policy?

Step-by-step explanation:

we are going to use direct proportionality to solve this problem

by relating Randy's payment to a variable x.

here is how it goes

given that

Wanda annual salary is  $37,500 and pays $18.75

Randy's annual salary is  $47,000 and pays x

cross multiplying we have

37500x=47000*18.75

37500x=881250

x=881250/37500

x= $23.5

Randy expect to pay $23.5 for his policy

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.

emily solved for a part when she should have solved for the whole. 875,000 should be the numerator of the equivalent ratio. 70 x 12,500 is 875,000. so the answer is 100 x 12,500 which is 1,250,000.
