Question

Jeans ($48) Sweater ($42) Tennis Shoes ($69) T-Shirt ($21) Blouse ($52) Heather is shopping for back-to-school clothes. The items she plans to purchase are shown. Which is a good estimate of the amount of money that Heather will spend before tax? A) $150 B) $190 C) $200 D) $230

Answer 1

You can use rounding to figure this problem out. If the number in the ones place is 0 to 4, round down to the nearest tens place; if the number in the ones place in 5 to 9, round up to the nearest tens place.

48 rounds to 50.
42 rounds to 40.
69 rounds to 70.
21 rounds to 20.
52 rounds to 50.

Now use mental math to estimate the cost (50 + 40 + 70 + 20 + 50). Heather will spend about $230.

Answer:
D) $230

Answer 2

Answer:

The answer is D) 230

Step-by-step explanation:

If each amount is rounded to the nearest 10 dollars the result is:

$50 + $40 + $70 + $20 + $50 = $230
