A carpenter purchased 25.25 feet of hardwood at \$25.20 per foot, and 3 types of trim molding:
2.6 feet \$1.90 per foot, 2.8 feet
at \$3.90 per foot, 7.5 feet at \$4.90 per foot.

How much did he spend on this purchase?

• Math -

25.25 * 25.2 = ?
2.6 * 1.9 = ?
2.8 * 3.9 = ?
7.5 * 4.9 = ?

• Math -

Okay, so after I added up the total sums together i got \$688.91 that was spent on the purchase. Is this correct?

• Math -

It can't be correct.

The hardwood alone cost \$636.30
25.25 * 25.2 = \$636.3

• Math -

I doulbe checked my math several of times just to make sure I gave the correct answer

25.35*25.2= \$636.30
2.6*1.9=\$4.94
2.8*3.9= \$10.92
7.5* 4.9= \$36.75

636.30 + 4.94 + 10.92 + 36.75= 688.91

So am I correct, or am I doing something wrong still?
