Question

Sandra bought a tube of toothpaste for $1.89, shampoo for $3.19 and a jar of peanuts for $2.29 from the local supermarket. Using rounding to the nearest whole number, estimate the total cost of her purchases.

Answer 1

to find the total cost, you need to add these numbers together


`1.89 + 3.19 + 2.29 = 7.37`
you get 7.37 as your answer, but you need to round this to the nearest whole number.

rounding 7.37 will make it 7.

the total cost is about $7

Answer 2
