Problem Solving
Jane makes 20 equal payments to buy a cd player that sells for $180.How much is each payment?
Justine makes 30 equal payments to buy a car that sells for $15,000.How much is each payment?
<<Estimate each Quotient!>>
To how many significant figures? Do the division
<<Jane makes 20 equal payments to buy a cd player that sells for $180.How much is each payment?>>
If it is an interest free purchase, divide $180 by 20
<<Justine makes 30 equal payments to buy a car that sells for $15,000.How much is each payment?>>
That depends upon the car loan interest rate. It varies depending upon what promotion is going on to clear cars out of the lot.
I hope this is not an example of home schooling.
To estimate each quotient, you need to perform the division and round the answer to the desired number of significant figures. Here are the estimates for each division:
1. 717/9 ≈ 79.67 (rounded to two decimal places)
2. 463/90 ≈ 5.14
3. 12.398/4.1 ≈ 3.02
4. 56.784/7.9 ≈ 7.19
5. 57.36/9.32 ≈ 6.15
6. 363.68/3.6 ≈ 101.02
7. 349/7.4 ≈ 47.16
8. 249/81 ≈ 3.07
9. 162.58/4.4 ≈ 36.95
10. 481.4/64 ≈ 7.52
11. 468.65/8.43 ≈ 55.58
12. 311.24/5.2 ≈ 59.85
13. 638/8.2 ≈ 77.80
14. 2,322/70 ≈ 33.17
15. 534.82/9.1 ≈ 58.67
16. 34.594/4.6 ≈ 7.53
17. 409.4/48.4 ≈ 8.45
18. 364.56/69.3 ≈ 5.26
For the problem-solving questions:
1. Jane makes 20 equal payments to buy a CD player that sells for $180. Each payment would be $180/20 = $9.
2. Justine makes 30 equal payments to buy a car that sells for $15,000. The amount of each payment depends on the car loan interest rate, which is not provided. You would need to know the interest rate to calculate the exact amount of each payment.
