At Ralphs Italian Ices, 145 sundaes were sold in June. Sales were up 23% in July, How many sundaes were sold in July?​
elena-s [515]
178 sundaes were sold in July.

To calculate a percentage, we convert to a decimal by dividing by 100. So 23% = 0.23

145 x 0.23 = 33.35 This is how many more sundaes were sold in July than June. We need to add the 145 sold in June to the increased number to find July’s total.
145 + 33.35 = 178.35

You can’t sell .035/ roughly a third of a sundae, so we round to the whole number.

Simplify the expression: y9 * y-2
agasfer [191]

Answer:

y^7

Step-by-step explanation:

If we want to simplify the expression y^9 \cdot y^{-2}, we have to note that exponent rules state that x^a \cdot x^b = x^{a+b}<em>.</em>

<em />

<em>This means that if we add the exponents, that will be what we raise y to the power of</em>.

9 + -2 = 9-2 = 7

So y^7.

Hope this helped!
