Is the number of coupons Querida gave away in Sunday proportional to the number of hours she worked that day? Hours worked on Sunday 1 -2 -3 4 coupons given away on Sunday.

Answer 1

The number of coupons Querida gave away in Sunday is proportional to the number of hours she worked that day.

Explanation:

It is provided that on Sunday Querida gave away about 52 coupons an hour.

Compute the number of coupons given away for different hours as follows:

Number of hours : 1 2 3 4

Number of Coupons : 52 104 156 208

Compute the number of coupons given away per hour provided that Querida worked 2 hours, 3 hours and 4 hours on Sunday as follows:

`\text{Number of coupons given away per hour}=(104)/(2)=52\ \text{coupon/hour}`

`\text{Number of coupons given away per hour}=(156)/(3)=52\ \text{coupon/hour}`

`\text{Number of coupons given away per hour}=(208)/(4)=52\ \text{coupon/hour}`

Thus, the number of coupons Querida gave away in Sunday is proportional to the number of hours she worked that day.
