Answer: 0.10d + 0.05n
Note: this value expression is in dollars (not cents)
If you want the expression in cents instead of dollars, then it would be 10d+5n

--------------------------------------------------------------------------------

The value of just the dimes only is 0.10d dollars
The value of just the nickels only is 0.05n dollars
Combined the total value is 0.10d+0.05n dollars

Which strategy could be used to solve 14 × 32? A. (14 × 3) + (14 × 2) = B. (14 + 3) + (14 + 2) = C. (4 × 32) + (10 × 32) = D. (4
sergey [27]
Hi there!

The answer is C.
14 × 32 = (4 × 32) + (10 × 32) = 128 + 320 = 448

In the first step we splitted 14 up into two different parts that are easily multipliable. These two parts are 4 and 10. She must multiply 32 first by 4 and then we must multiply 32 by 10. This way we multiplied it a total of 14 times, just as we should.
14 × 32 = (4 × 32) + (10 × 32)

If 30g of sugar is needed to make 4 cakes how much grams of sugar is needed to make 7 cakes
arsen [322]
There's two ways to do this.

The first way:
Work out the amount of sugar needed to make one cake, and then multiply that by 7.

30 grams ÷ 4 cakes = 7.5 grams for 1 cake.
7.5 grams × 7 cakes = 52.5 grams for 7 cakes.

The second way:
Work out the ratio of sugar:cake by doing 7 ÷ 4, and then multiplying that value by 30.

7 cakes ÷ 4 cakes = 1.75
1.75 × 30 grams = 52.5 grams for 7 cakes. 

Either way, the answer is 52.5 grams.
